High-performance coherent population trapping atomic clock with direct-modulation distributed Bragg reflector laser
Peter Yun, Qinglin Li, Qiang Hao +7
The coherent population trapping (CPT) atomic clock is very promising for use in next-generation spaceborne applications owing to its compactness and high performance. In this pape…
Two-dimensional Cold Electron Transport for Steep-slope Transistors
Maomao Liu, Hemendra Nath Jaiswal, Simran Shahi +10
Room-temperature Fermi-Dirac electron thermal excitation in conventional three-dimensional (3D) or two-dimensional (2D) semiconductors generates hot electrons with a relatively lon…
Spin filtering in germanium/silicon core/shell nanowires with pseudo-helical gap
Jian Sun, Russell S. Deacon, Xiaochi Liu +2
Semiconductors with strong spin-orbit interactions can exhibit a helical gap with spin-momentum locking opened by a magnetic field. Such a gap is highly spin selective as a result…
