Origin of 2DEG in GaN HEMT

This video talks about the physics behind the origin of Two Dimensional Electron Gas (2DEG ) in AlGaN/GaN High Electron Mobility Transistor (HEMT). The conventional source has been viewed from a different perspective. Please follow this paper for all the details: Formation of two-dimensional electron gas at AlGaN/GaN heterostructure and the derivation of its sheet density expression (H Xiao-Guang et al.)
