Robust Aluminum Nitride Passivation of Silicon Carbide with Near-Surface Quantum Emitters for Quantum Computing and Sensing Applications
Cyrille Armel Sayou Ngomsi, Sai Krishna Narayanan, Pratibha Dev
Silicon carbide (SiC) hosts a number of point defects that are being explored as single-photon emitters for quantum applications. Unfortunately, these quantum emitters lose their p…
Tuning spin currents in collinear antiferromagnets and altermagnets
Sajjan Sheoran, Pratibha Dev
Spin current generation through non-relativistic spin splittings, found in uncompensated magnets and d-wave altermagnets, is desirable for low-power spintronics. Such spin currents…
The influence of nitrogen doping and annealing on the silicon vacancy in 4H-SiC
Samuel G. Carter, Infiter Tathfif, Charity Burgess +3
The silicon vacancy () in 4H-SiC at its cubic site (V2-center) has shown significant promise for quantum technologies, due to coherent spin states, the mature material syst…
Spontaneous Anomalous Hall Effect in Two-Dimensional Altermagnets
Sajjan Sheoran, Pratibha Dev
The anomalous Hall effect (AHE) is an efficient tool for detecting the Néel vector in collinear compensated magnets with spin-split bands, known as altermagnets (AMs). Here, we es…
