Journal ArticleDOI
Two-Dimensional Transition Metal Dichalcogenides and Their Charge Carrier Mobilities in Field-Effect Transistors
Sohail Ahmed,Jiabao Yi +1 more
TL;DR: This review mainly focuses on the recent advances in charge carrier mobility and the challenges to achieve high mobility in the electronic devices based on 2D-TMDC materials and also includes an introduction of 2D materials along with the synthesis techniques.
Journal ArticleDOI
Inducing High Coercivity in MoS2 Nanosheets by Transition Element Doping
Sohail Ahmed,Xiang Ding,Nina Bao,Pengju Bian,Rongkun Zheng,Yiren Wang,Peter P. Murmu,John Kennedy,Rong Liu,Haiming Fan,Kiyonori Suzuki,Jun Ding,Jiabao Yi +12 more
TL;DR: In this paper, a very large coercivity up to 1.87 kOe has been observed in 5 at% vanadium doped MoS2, which may attribute to a combination effect of localized charge transfer between V and S ions, pinning effect due to the in-between defects, stress induced by doping, and shape anisotropy due to two-dimensional nature of MoS 2 ribbons.
Journal ArticleDOI
A Distributed Multi-Agent RL-Based Autonomous Spectrum Allocation Scheme in D2D Enabled Multi-Tier HetNets
TL;DR: The proposed scheme enables the D2D users to achieve higher throughput and SE, higher signal-to-interference-plus-noise ratio and low outage ratio for cellular users, and better computational time efficiency and performs well in the dense multi-tier HetNets.
Journal ArticleDOI
Enhanced ferromagnetism in WS2 via defect engineering
TL;DR: In this paper, the authors employed WS2 powders as an example to study the relationship between defects and magnetism by annealing the powders under reducing atmosphere and found that pristine WS2 powder showed weak ferromagnetism at room temperature.
Journal ArticleDOI
Magnetic properties of Co doped WSe2 by implantation
Sohail Ahmed,Xiang Ding,Peter P. Murmu,Nina N Bao,Rong Liu,John Kennedy,Jeak Ling Ding,Jiabao Yi +7 more
TL;DR: In this paper, the potential of transition metal doped 2D WSe2 as a 2D dilute magnetic semiconductor has been explored experimentally by using a physical implantation method.
