Enhancing electron mobility at the LaAlO₃ /SrTiO₃ interface by surface control.

Yanwu Xie1, Christopher Bell, Yasuyuki Hikita, Satoshi Harashima, Harold Y Hwang.   

Abstract

Mobility of electrons confined at the LaAlO₃ /SrTiO₃ interface is significantly enhanced by surface control using surface charges and adsorbates, reaching a low temperature value more than 20 000 cm(2) V(-1) s(-1) . A uniform trend that mobility increases with decreasing sheet carrier density is observed.
