Although the 2DEG,at least at Interfaces at which the theoretically expected mobile charge density is experimentally observed,perfectly compensates for the bound charge at the Interface,some attention must be paid to the free polar surface for structures of type RTiO3/SrTiO3 or LaAlO3/SrTiO3,for which the Oxide with the polar surface,i.e.,RTiO3 or LaAlO3,is the top layer.(¾äÖеÄÊý×Ö¶¼Îª½Ç±ê£©
