Does P-type Ohmic Contact Exist in WSe2-metal Interfaces?
Yangyang Wang, Ruoxi Yang, Ruge Quhe +9
Formation of low-resistance metal contacts is the biggest challenge that masks the intrinsic exceptional electronic properties of 2D WSe2 devices. We present the first comparative…
Monolayer Phosphorene-Metal Interfaces
Yuanyuan Pan, Yangyang Wang, Meng Ye +9
Recently, phosphorene electronic and optoelectronic prototype devices have been fabricated with various metal electrodes. We systematically explore for the first time the contact p…
Silicene on Substrates: A Theoretical Perspective
Hongxia Zhong, Ruge Quhe, Yangyang Wang +2
Silicene, as the silicon analog of graphene, has been successfully fabricated by epitaxial growing on various substrates. Similar to free-standing graphene, free-standing silicene…
Silicene Spintronics
Yangyang Wang, Ruge Quhe, Dapeng Yu +2
Spintronics involves the study of active control and manipulation of spin degrees of freedom in solid-state systems. The fascinating spin-resolved properties of graphene motivate n…
Silicene Nanomesh
Feng Pan, Yangyang Wang, Kaili Jiang +8
Similar to graphene, zero band gap limits the application of silicene in nanoelectronics despite of its high carrier mobility. By using first-principles calculations, we reveal tha…
Interfacial Properties of Monolayer and Bilayer MoS2 Contacts with Metals: Beyond the Energy Band Calculations
Hongxia Zhong, Zeyuan Ni, Yangyang Wang +8
Although many prototype devices based on two-dimensional (2D) MoS2 have been fabricated and wafer scale growth of 2D MoS2 has been realized, the fundamental nature of 2D MoS2-metal…
