Novel polymorphic phase of BaCu2As2: impact of flux for new phase formation in crystal growth
Hanlin Wu, Sheng Li, Zheng Wu +6
In this work, we have thoroughly studied the effects of flux composition and temperature on the crystal growth of the BaCu2As2 compound. While Pb and CuAs self-flux produce the wel…
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…
Two-Dimensional h-BN and MoS2 as Diffusion Barriers for Ultra-Scaled Copper Interconnects
Chun-Li Lo, Massimo Catalano, Kirby K. H. Smithe +5
Copper interconnects in modern integrated circuits require ultra-thin barriers to prevent intermixing of Cu with surrounding dielectric materials. Conventional barriers rely on met…
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…
Field-effect transistors made from solution-grown two-dimensional tellurene
Yixiu Wang, Gang Qiu, Ruoxing Wang +9
The reliable production of two-dimensional crystals is essential for the development of new technologies based on 2D materials. However, current synthesis methods suffer from a var…
Covalent Nitrogen Doping and Compressive Strain in MoS2 by Remote N2 Plasma Exposure
Angelica Azcatl, Xiaoye Qin, Abhijith Prakash +11
Controllable doping of two-dimensional materials is highly desired for ideal device performance in both hetero- and p-n homo-junctions. Herein, we propose an effective strategy for…
Formation of hexagonal Boron Nitride on Graphene-covered Copper Surfaces
Devashish P. Gopalan, Patrick C. Mende, Sergio C. de la Barrera +10
Graphene-covered copper surfaces have been exposed to borazine, (BH)3(NH)3, with the resulting surfaces characterized by low-energy electron microscopy. Although the intent of the…
Atomically Thin Resonant Tunnel Diodes built from Synthetic van der Waals Heterostructures
Yu-Chuan Lin, Ram Krishna Ghosh, Rafik Addou +10
Vertical integration of two-dimensional van der Waals materials is predicted to lead to novel electronic and optical properties not found in the constituent layers. Here, we presen…
