Subcycle Wannier-Stark Localization by Mid-Infrared Bias in Gallium Arsenide
The fundamental interband absorption in gallium arsenide shows a strong blue shift when biased by mid-infrared transients exceeding 10 MV/cm. This subcycle feature is induced by the localization of electronic wavefunctions from 3D to 2D.
