Incommensurate Transverse Peierls Transition
F. Z. Yang, K. F. Luo, Weizhe Zhang +19
In one-dimensional quantum materials, conducting electrons and the underlying lattices can undergo a spontaneous translational symmetry breaking, known as Peierls transition. For n…
Charge Density Waves in the 2.5-Dimensional Quantum Heterostructure
F. Z. Yang, T. T. Zhang, F. Y. Meng +8
Charge density wave (CDW) and their interplay with correlated and topological quantum states are forefront of condensed matter research. The 4-TaS is a CDW ordered quant…
Spin-phonon coupling driven Charge density wave in a Kagome Magnet
H. Miao, T. T. Zhang, H. X. Li +14
The intertwining between spin, charge, and lattice degrees of freedom can give rise to unusual macroscopic quantum states, including high-temperature superconductivity and quantum…
Electrical spin injection into InGaAs/GaAs quantum wells: a comparison between MgO tunnel barriers grown by sputtering and molecular beam epitaxy methods
P. Barate, S. Liang, T. T. Zhang +16
An efficient electrical spin injection into an InGaAs/GaAs quantum well light emitting diode is demonstrated thanks to a CoFeB/MgO spin injector. The textured MgO tunnel barrier is…
