FIG. 3.15 Band diagrams of (a) valence band and (b) conduction band in the GaN/InGaN p–i–n structure. Carrier wavefunctions are not centrosymmetric due to polarization. E p and E n are the first bound states in the valence and conduction bands More about this image found in Band diagrams of (a) valence band and (b) conduction band in the GaN/InGaN ...

FIG. 3.20 Band diagrams of the AlGaN/GaN heterostructure for HEMT. Strained AlGaN is grown pseudomorphically on relaxed GaN. A positive polarization charge ( + σ ) is induced at the interface, which attracts electrons and forms 2DEG. More about this image found in Band diagrams of the AlGaN/GaN heterostructure for HEMT. Strained AlGaN is ...
