Interaction between Surface Acoustic Wave and Quantum Hall Effects
Xiao Liu, Mengmeng Wu, Renfei Wang +6
Surface Acoustic Wave (SAW) is a powerful technique for investigating quantum phases appearing in two-dimensional electron systems. The electrons respond to the piezoelectric field…

Probing quantum phases in ultra-high-mobility two-dimensional electron systems using surface acoustic waves
Mengmeng Wu, Xiao Liu, Renfei Wang +6
Transport measurement, which applies an electric field and studies the migration of charged particles, i.e. the current, is the most widely used technique in condensed matter studi…
