Sub-Thermionic Switching in a Negative-Capacitance Bandgap-Change Field-Effect Transistor
Rahul B Awale, Mike Klymenko, Yuefeng Yin +3
Overcoming the approximately 60~mV/dec Boltzmann limit of the subthreshold swing remains a central challenge for low-power nanoelectronics. Negative-capacitance field-effect transi…
Generic Approach to Intrinsic Magnetic Second-order Topological Insulators via Inverted Orbitals
Zhao Liu, Bing Liu, Yuefeng Yin +1
The integration of intrinsically magnetic and topologically nontrivial two-dimensional materials holds tantalizing prospects for the exotic quantum anomalous Hall insulators and ma…
Extracting unconventional spin texture in two dimensional topological crystalline insulator bismuthene via tuning bulk-edge interactions
Yuefeng Yin, Chutian Wang, Michael S. Fuhrer +1

Coherent backscattering in the topological Hall effect
Hong Liu, Rhonald Burgos Atencia, Nikhil Medhekar +1
The mutual interplay between electron transport and magnetism has attracted considerable attention in recent years, primarily motivated by strategies to manipulate magnetic degrees…
Proposal for a Negative Capacitance Topological Quantum Field-Effect Transistor
Michael S. Fuhrer, Mark T. Edmonds, Dimitrie Culcer +5
A topological quantum field effect transistor (TQFET) uses electric field to switch a material from topological insulator ("on", with conducting edge states) to a conventional insu…
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…
Magnesium-intercalated graphene on SiC: highly n-doped air-stable bilayer graphene at extreme displacement fields
