摘要
Dielectric and polar properties of aluminum nitride (AlN) thin films epitaxially grown on differently oriented silicon substrates with the p-type conduction and a buffer silicon carbide (SiC) layer and on vicinal planes are investigated. The results of studies of the polar properties by two independent methods-the dynamic pyroelectric effect and the piezoresponse force microscopy-show that the SiC buffer layer application considerably improves polar properties of the aluminum nitride thin layer.
