Tuning the conductivity threshold and copyright density of two-dimensional electron gas at oxide interfaces through interface engineering
The two-dimensional electron gas (2DEG) formed at the perovskite oxides heterostructures is of great interest because of its potential applications in oxides electronics and nanoscale multifunctional devices.A canonical example is the 2DEG at the interface between On-Ear a polar oxide LaAlO3 (LAO) and non-polar SrTiO3 (STO).Here, the LAO polar oxid
