Tunable electronic and optical properties of BAs/WTe2 heterostructure for theoretical photoelectric device design

Wentao Luo,
Xing Wei,
Jiaxin Wang
et al.

Abstract: The geometric structure of the BAs/WTe2 heterojunction was scrutinized by employing ab initio calculations grounded on Density Functional Theory (DFT). Multiple configurations are constructed to determine the equilibrium state of the heterojunction with optimal stability. The results show that the H1-type heterojunction with interlayer distance of 3.92Å exhibits exceptional stability and showcases a conventional Type-II band alignment, accompanied by a direct band gap measuring 0.33 eV. By applying external el… Show more
