WebJul 19, 2012 · In gallium nitride (GaN), n-type doping is straightforward, and can be achieved by adding elements such as silicon or germanium. However, p-type doping is still imperfect. 1 Intriguingly, magnesium (Mg) is the only impurity that can produce p-type GaN, and it suffers from significant limitations. Mg has a much larger ionization energy … WebJan 1, 2024 · The results indicate that Si and Sn act as effective n type dopants by substituting Ga atoms. Besides, Si has a higher doping efficiency due to the lower formation energy. Mg atoms enter into α-Ga 2 O 3 mainly by substituting Ga atoms and act as an acceptor impurity.

In semiconductor physics, an acceptor is a dopant atom that when substituted into a semiconductor lattice forms a p-type region. When silicon (Si), having four valence electrons, is doped with elements from group III of the periodic table, such as boron (B) and aluminium (Al), both having three valence electrons, a p-type semiconductor is formed. These dopant elements represent trivalent impurities. Other trivalent d…
