using a bandstructure–engineered photo–generated carrier extractor. The 100% cut–off wavelengths of theses BECX photodetectors were ~2.1 μm at 150K and ~2.4 μm at 300K. The visible cut−on wavelength of the BECX devices
A type-II Dirac fermion is a special type of Dirac fermion that has a specific electronic band structure resembling a tilted cone. Prior theoretical calculations suggested that they could be lurking in palladium ditelluride, says Han-Jin Noh of Chonnam National University, who is a member of the...
W-type structures feature two materials that form a type-II band alignment when combined as a hetero structure as sketched in Fig. 1. In this configuration, one of the materials must have a higher valence band edge and the other one a lower conduction band edge to confine the respective ...

Semiconducting heterostructures with type-II band structure have attracted much attention due to their novel physical properties and wide applications in optoelectronics. Herein, we report, for the first time, a controlled synthesis of t... X Huang,YQ Yu,J Xia,... - 《Nanoscale》 被引量: 8发...
The band structure in the so called type I WSM like graphene1 in 2D and ZrTe5 in 3D2,3,4,5,6,7,8,9,10,11,12,13,14, is characterized by appearance of linear dispersion relation, cones around several Dirac points, due to the band inversion. This is qualitatively distinct from ...
