Abstract


ZnO thin layers were grown from zinc acetate dissolved in methanol-acetic acid-water solution with the molarity of 0.2M by using the pulverization method in an argon flow at the temperatures of 250-450°C. The temperature dependence of electrical and optical properties of the obtained layers were studied. The optical transmittance at the wavelengths of (300 -1000) nm has the values of 80-85%. The resistivity of ZnO thin layers grown at 450°C decreases from 33W•cm to       0,028 W•cm after annealing in hydrogen at 450°C during an hour. The radiative recombination is related to the electron transitions to the deep levels and band to band transitions at the charge carriers transitions with the LO type phonons.


Keywords
