AB Invented in 1980, High Electron Mobility Transistors(HEMTs) are now widely used in high-frequency electronics. They are fabricated in different material systems and a possible new material for future devices is indium nitride (InN). InN HEMTs are considered very promising because of the good electron transport properties of the material predicted by Monte Carlo simulations. InN has a lower effective mass, higher mobility and higher peak drift velocity than GaN. Compared to (In)GaAs, the material also performs well. However, due to current problems with the InN material growth, the field of InN HEMTs is still at an early stage.
