Lattice Vibrational Modes and Phonon Thermal Conductivity of Monolayer MoS2
Yongqing Cai, Jinghua Lan, Gang Zhang +1
The anharmonic behavior of phonons and intrinsic thermal conductivity associated with the Umklapp scattering in monolayer MoS2 sheet are investigated via first-principles calculati…
Polarity Reversed Robust Carrier Mobility in Monolayer MoS2 Nanoribbons
Yongqing Cai, Gang Zhang, Yong-Wei Zhang
Using first-principles calculations and deformation potential theory, we investigate the intrinsic carrier mobility (μ) of monolayer MoS2 sheet and nanoribbons. In contrast to the…
NIR Schottky Photodetectors Based on Individual Single-Crystalline GeSe Nanosheet
Bablu Mukherjee, Yongqing Cai, Hui Ru Tan +3
We have synthesized high-quality, micrometer-sized, single-crystal GeSe nanosheets using vapor transport and deposition techniques. Photoresponse is investigated based on mechanica…
Constructing Metallic Nanoroad on MoS2 Monolayer via Hydrogenation
Yongqing Cai, Zhaoqiang Bai, Hui Pan +3
Monolayer transition metal dichalcogenides recently emerge as a new family of two-dimensional material potentially suitable for numerous applications in electronic and optoelectron…
Thermal Stability and Electrical Control of Magnetization of Heusler/Oxide Interface and Non-collinear Spin Transport of Its Junction
Zhaoqiang Bai, Lei Shen, Yongqing Cai +4
Towards next-generation spintronics devices, such as computer memories and logic chips, it is necessary to satisfy high thermal stability, low-power consumption and high spin-polar…
All-Heusler giant-magnetoresistance junctions with matched energy bands and Fermi surfaces
Zhaoqiang Bai, Yongqing Cai, Lei Shen +2
We present an all-Heusler architecture which could be used as a rational design scheme for achieving high spin-filtering efficiency in the current-perpendicular-to-plane giant magn…
