Sb thin films have attracted wide interest due to their tunable band structure, topological phases, high electron mobility, and thermoelectric properties. We successfully grow epitaxial Sb thin films on a closely lattice-matched GaSb(001) surface by

Autor: Hyeongwoo Lee, Yeonjeong Koo, Jinseong Choi, Shailabh Kumar, Hyoung-Taek Lee, Gangseon Ji, Soo Ho Choi, Mingu Kang, Ki Kang Kim, Hyeong-Ryeol Park, Hyuck Choo, Kyoung-Duck Park
Publikováno v: Science advances. 8(5)
Understanding and controlling the nanoscale transport of excitonic quasiparticles in atomically thin two-dimensional (2D) semiconductors are crucial to produce highly efficient nano-excitonic devices. Here, we present a nanogap device to selectively
