Impurity-induced anisotropic semiconductor-semimetal transition in monolayer biased black phosphorus

Substrate-induced strain and exchange field effects on the electronic and thermal properties of monolayer β12-borophene

“…47 In this context, the analytical continuation in the complex plane is achieved by transforming iE to E + iZ. To derive EDOS, we start with the usual definition of DOS of a system, which is commonly described by DðEÞ ¼ P [48][49][50][51] with E m being the normalized eigenvalues supposed to be countable for simplicity with m counter (m = 1-5 in our system). Using the definition of the Dirac delta function dðxÞ ¼ lim…”

Spin-splitting effects on the interband optical conductivity and activity of phosphorene

“…Or a uniform perpendicular electric field originating from gate voltage results in an increase of the band gap 41 . Also, an anisotropic electronic phase transition has been reported in MBP in the presence of dilute charged impurity 42 . Besides the electronic properties, due to the inherent highly dispersive electronic band structure of MBP, a large optical conductivity has been obtained in MBP 25 of which in the absorption spectra the absorption peaks for the xand y-direction take place in different optical frequencies.…”
