| 1 | Edge-Dependent Electronic and Magnetic Characteristics of Freestanding β_(12)-Borophene Nanoribbons显示文摘This work presents an investigation of nanoribbons cut from β_(12)-borophene sheets by applying the density functional theory. In particular, the electronic and magnetic properties of borophene nanoribbons(BNR) are studied. It is found that all the ribbons considered in this work behave as metals, which is in good agreement with the recent experimental results. β_(12)-BNR has significant diversity due to the existence of five boron atoms in a unit cell of the sheet. The magnetic properties of the ribbons are strongly dependent on the cutting direction and edge profile. It is interesting that a ribbon with a specific width can behave as a normal or a ferromagnetic metal with magnetization at just one edge or two edges. Spin anisotropy is observed in some ribbons, and the magnetic moment is not found to be the same in both edges in an antiferromagnetic configuration. This effect stems from the edge asymmetry of the ribbons and results in the breaking of spin degeneracy in the band structure. Our findings show that β_(12) BNRs are potential candidates for next-generation spintronic devices. | Sahar Izadi Vishkayi Meysam Bagheri Tagani | 2018 | Nano-Micro Letters2018,10,1: | 1 |

| 9 | Thermoelectric Properties of Single Molecule Junction in Presence of Dephasing and Different Coupling Geometries显示文摘The thermoelectric properties of a benzene molecule coupled to three-dimensional metallic electrodes are examined in the presence of dephasing processes using Green function formalism in the linear response regime. The three different kind of configurations(ortho, meta and para) are taken into account for the coupling between the molecule and electrodes. Results show that the thermoelectric properties of the single molecular junction are strongly dependent on the coupling geometry. Our results predict that the thermoelectric efficiency is increased in specific geometry as a consequence of interference effects. It is found that the dephasing effects result in the reduction of the thermoelectric efficiency. | Z.Golsanamlou M.Bagheri Tagani H.Rahimpour Soleimani | 2015 | Communications in Theoretical Physics2015,,9: | 0 |
| 10 | Selective formation of ultrathin PbSe on Ag(111)显示文摘Two-dimensional(2D)semiconductors,such as lead selenide(PbSe),locate at the key position of next-generation devices.However,the ultrathin PbSe is still rarely reported experimentally,particularly on metal substrates.Here,we report the ultrathin PbSe synthesized via sequential molecular beam epitaxy on Ag(111).The scanning tunneling microscopy is used to resolve the atomic structure and confirms the selective formation of ultrathin PbSe through the reaction between Ag5Se2 and Pb,as further evidenced by the theoretical calculation.It is also found that the increased accumulation of Pb leads to the improved quality of PbSe with larger and more uniform films.The detailed analysis demonstrates the bilayer structure of synthesized PbSe,which could be deemed to achieve the 2D limit.The differential conductance spectrum reveals a metallic feature of the PbSe film,indicating a certain interaction between PbSe and Ag(111).Moreover,the moirépattern originated from the lattice mismatch between PbSe and Ag(111)is observed,and this moirésystem provides the opportunity for studying physics under periodical modulation and for device applications.Our work illustrates a pathway to selectively synthesize ultrathin PbSe on metal surfaces and suggests a 2D experimental platform to explore PbSe-based opto-electronic and thermoelectric phenomena. | 王静 Meysam Bagheri Tagani 张力 夏雨 吴奇龙 黎博 田麒玮 田园 殷隆晶 张利杰 秦志辉 | 2022 | Chinese Physics B2022,31,9: | 0 |
| 11 | Charge and spin-dependent thermal efficiency of polythiophene molecular junction in presence of dephasing显示文摘The charge and spin-dependent thermoelectric properties of different lengths of polythiophene in a molecular junction are investigated using the B ¨uttiker probe method within Green function formalism in linear response regime. The coupling of the molecular chain to three-dimensional ferromagnetic electrodes is described by a tight-binding model for both parallel and antiparallel spin configurations. The decrease of height of transmission probability peaks and thermoelectric coefficients are observed in the presence of the B ¨uttiker probes. The reduction is more intensive in the strong dephased chains.Results show that the spin magnetothermopower is bigger than the charge magnetothermopower due to the larger difference between the spin thermopowers with respect to the charge ones. In addition, we observed that the kind of carriers participating in the thermoelectric transport depends on the number of the thiophene rings. | Z.Golsanamlou M.Bagheri Tagani H.Rahimpour Soleimani | 2015 | Chinese Physics B2015,24,10: | 0 |
| 12 | Improvement of the thermoelectric efficiency of pyrene-based molecular junction with doping engineering显示文摘In this study, the thermoelectric properties of pyrene molecule doped with boron and nitrogen atom at different sites of molecule are investigated using density functional theory and none-equilibrium Green's function formalism in the linear response regime. Our calculations show that when the impurities are added to the edge of the molecule, the anti-resonant peaks will appear in the transmission diagram in the vicinity of the Fermi energy level. So it increases the thermoelectric figure of merit of the system in comparison with the one that the impurity is located in the center of molecule. Additionally,the seebeck coefficient signs are not the same among the B, N, and N & B doped devices, indicating that the types of the carriers can be changed with different types of doping. | Mohammad Farid Jamali Meysam Bagheri Tagani Hamid Rahimpour Soleimani | 2017 | Chinese Physics B2017,26,12: | 0 |
| 13 | Phonon-dependent transport through a serially coupled double quantum dot system显示文摘Using Keldysh nonequilibrium Green function formalism and mapping a many-body electron–phonon interaction onto a one body problem, the electron transport through a serially coupled double quantum dot system is analyzed. The influence of the electron–phonon interaction, temperature, detuning, and interdot tunneling on the transmission coefficient and current is studied. Our results show that the electron–phonon interaction results in the appearance of the side peaks in the transmission coefficient, whose height is strongly dependent on the phonon temperature. We have also found that the inequality of the electron–phonon interaction strength in two dots gives rise to an asymmetry in the current–voltage characteristic. In addition, the temperature difference between the phonon and electron subsystems results in the reduction of the saturated current and the destruction of the step-like behavior of the current. It is also observed that the detuning can improve the magnitude of the current by compensating the mismatch of the quantum dots energy levels induced by the electron–phonon interaction. | M.Bagheri Tagani H.Rahimpour Soleimani | 2014 | Chinese Physics B2014,23,5: | 0 |
| 14 | Impact of coupling geometry on thermoelectric properties of oligophenyl-base transistor显示文摘Thermal and electron transport through organic molecules attached to three-dimensional gold electrodes in two different configurations, namely para and meta with thiol-terminated junctions is studied theoretically in the linear response regime using Green's function formalism. We used thiol-terminated(–SH bond) benzene units and found a positive thermopower because the highest occupied molecular orbital(HOMO) is near the Fermi energy level. We investigated the influence of molecular length and molecular junction geometry on the thermoelectric properties. Our results show that the thermoelectric properties are highly sensitive to the coupling geometry and the molecular length. In addition, we observed that the interference effects and increasing molecular length can increase the thermoelectric efficiency of device in a specific configuration. | S Ramezani Akbarabadi H Rahimpour Soleimani M Bagheri Tagani Z Golsanamlou | 2017 | Chinese Physics B2017,26,2: | 0 |
