Transport evidence of the three-dimensional Dirac semimetal phase in doped -Sn grown by molecular beam epitaxy
Yuanfeng Ding, Bingxin Li, Chen Li +3
We report the quantum transport properties of the -Sn films grown on CdTe (001) substrates by molecular beam epitaxy. The -Sn films are doped with phosphorus to tune the Ferm…
1550 nm compatible ultrafast photoconductive material based on a GaAs/ErAs/GaAs heterostructure
Kedong Zhang, Yiwen Li, Yifeng Ren +8
The sub-bandgap absorption and ultrafast relaxation in a GaAs/ErAs/GaAs heterostructure are reported. The infrared absorption and 1550 nm-excited ultrafast photo-response are studi…
Large magnetoresistance observed in α-Sn/InSb heterostructures
Yuanfeng Ding, Huanhuan Song, Junwei Huang +7
In this study, we report the epitaxial growth of a series of α-Sn films on InSb substrate by molecular beam epitaxy (MBE) with thickness varying from 10 nm to 400 nm. High qualitie…
Signature of Many-Body Localization of Phonons in Strongly Disordered Superlattices
Thanh Nguyen, Nina Andrejevic, Hoi Chun Po +17
Many-body localization (MBL) has attracted significant attention due to its immunity to thermalization, role in logarithmic entanglement entropy growth, and opportunities to reach…
Thermal Stability Enhancement in Epitaxial α-Sn Films by Strain Engineering
Huanhuan Song, Jinshan Yao, Yuanfeng Ding +5
Exploring new topological materials with large topological nontrivial bandgaps and simple composition is attractive for both theoretical investigation and experimental realization.…
Self-assembled ErSb nanostructures of tunable shape and orientation: growth and plasmonic properties
Hong Lu, Daniel G. Ouellette, Sascha Preu +5
Self-assembled, semimetallic ErSb single crystal nanostructures, grown by molecular beam epitaxy, are embedded within a semiconductor GaSb matrix. Formation, evolution and orientat…
