Magneto-optical characterization of GeSn and GeSn/SiGeSn heterostructures
Mehdi Ashrafganjoie, Kelvin Dsouza, Prithu Bhatnagar +9
Hole spin qubits in germanium (Ge)-based heterostructures have demonstrated their potential for scalable quantum information processing using all-electrical gate operations. Furthe…
Observation of Kondo hybridization wave in UTe2
Xin Yu, Shuikang Yu, Zheyu Wu +9
Condensed matter systems with strong electronic correlations often manifest a variety of intertwined ordered phases of charge, spin, orbital and other degrees of freedom. As a prot…
Neutralizing Optical Defects in GeSn
Nirosh M. Eldose, Dinesh Baral, Diandian Zhang +7
Reports of photoluminescence from GeSn grown on Ge substrates by molecular beam epitaxy have been limited. We find that one limiting factor to observing photoluminescence is due to…
