| Abstract: | Recently,the quasi-two-dimensional electron gas (q2DEG)confined at the interface between LaAlO3and SrTiO3has attracted significant attention.In this paper,we briefly review experimental methods that have been used to tune the carrier density and mobility of this q2DEG.These methods can be classified into two categories:growth-related tuning (i.e.substrate,growth temperature,oxygen pressure,post-annealing,LaAlO3thickness,stoichiometry,and capping layers)and post-growth tuning (i.e.electrostatic field gating,conductive atomic force microscopy and surface adsorbates).Taken together,these methods enable the broad tuning of the electronic properties of this interface. |
