    GaN based HEMT structures exhibit better parameters than Si based transistor structures. The most important are GaN based HEMT in high power and high frequency application. Structures were grown by MOVPE in AIXTRON apparatus on Si substrates. Resistance measurement on the buffer with contact distance 20µm exhibited current ≈ 10-11. We evaluated the uniformity of heterostructure grown on silicon substrate by evaluation of transistor properties on the base of dc parameters measurement. The uniformity of heterostructure growth, especially on silicon substrate is very challenging and need to be improve if GaN-based devices have to be start in serial production.
