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 cm2 V−1s−1. A uniform trend that mobility increases with decreasing sheet carrier density is observed.
