Atomically Controlled Tunable Doping in High Performance WSe2 Devices
Chin-Sheng Pang, Terry Y. T. Hung, Ava Khosravi +5
Two-dimensional transitional metal dichalcogenide (TMD) field-effect transistors (FETs) are promising candidates for future electronic applications, owing to their excellent transp…
Contact Engineering High Performance n-Type MoTe2 Transistors
Michal J. Mleczko, Andrew C. Yu, Christopher M. Smyth +7
Semiconducting MoTe2 is one of the few two-dimensional (2D) materials with a moderate band gap, similar to silicon. However, this material remains under-explored for 2D electronics…
Enhancing Interconnect Reliability and Performance by Converting Tantalum to 2D Layered Tantalum Sulfide at Low Temperature
Chun-Li Lo, Massimo Catalano, Ava Khosravi +9
The interconnect half-pitch size will reach ~20 nm in the coming sub-5 nm technology node. Meanwhile, the TaN/Ta (barrier/liner) bilayer stack has to be > 4 nm to ensure acceptable…
MBE growth of 2H-MoTe2 and 1T'-MoTe2 on 3D substrates
Suresh Vishwanath, Aditya Sundar, Xinyu Liu +17
MoTe2 is the least explored material in the Molybdenum-chalcogen family, which crystallizes in thermodynamically stable semiconducting 2H phase at \textless 500 C and 1T' metallic…
