摘要
Surface topography, dielectric and pyroelectric properties of semipolar AlN thin films are studied. The growth of AlN was carried out by hydride-chloride vapor phase epitaxy on hybrid SiC layers specially prepared for the growth of semipolar AlN layers. SiC layers were grown on Si substrates of p-type (KDB) with (100)-orientation. The dynamic pyroelectric response of the AlN layer was observed. The pyroelectric current kinetics was analyzed in the frequency range of 10-1000 Hz, and the calculated pyroelectric coefficient was nearly equal to 9 center dot 10(-10) C/(cm(2)K).
