Wavelength-Controlled Photocurrent Polarity Switching in BP-MoS Heterostructure
Himani Jawa, Sayantan Ghosh, Abin Varghese +2
Layered two-dimensional van der Waals (vdW) semiconductors and their heterostructures have been shown to exhibit positive photoconductance (PPC) in many studies. A few recent repor…
Near-Infrared and Visible-range Optoelectronics in 2D Hybrid Perovskite/Transition Metal Dichalcogenide Heterostructures
Abin Varghese, Yuefeng Yin, Mingchao Wang +2
The application of ultrathin two-dimensional (2D) perovskites in near-infrared and visible-range optoelectronics has been limited owing to their inherent wide bandgaps, large excit…
Large bandgap quantum anomalous hall insulator in a designer ferromagnet-topological insulator-ferromagnet heterostructure
Qile Li, Chi Xuan Trang, Weikang Wu +5
Combining magnetism and nontrivial band topology gives rise to quantum anomalous Hall (QAH) insulators and exotic quantum phases such as the QAH effect where current flows without…
Manifestation of strongly correlated electrons in a 2D kagome metal-organic framework
Dhaneesh Kumar, Jack Hellerstedt, Bernard Field +4
The kagome lattice, whose electronic valence band (VB) structure includes two Dirac bands and one flat band, offers a rich space to realise tuneable topological and strongly correl…
Localized Wannier function based tight-binding models for two-dimensional allotropes of bismuth
Qile Li, Jackson S. Smith, Yuefeng Yin +4
With its monoelemental composition, various crystalline forms and an inherently strong spin-orbit coupling, bismuth has been regarded as an ideal prototype material to expand our u…
Thickness dependent tuning of the Berry curvature in a ferromagnetic Weyl semimetal
Yao Zhang, Yuefeng Yin, Guy Dubuis +3
Magnetic Weyl semimetals with spontaneously broken time-reversal symmetry exhibit a large intrinsic anomalous Hall effect originating from the Berry curvature. To employ this large…
