Photoresponse of polycrystalline ZnO films deposited by r.f. bias sputtering
Thin Solid Films 261 (1995) 334-339,-0001,():
The photoresponse of polycrystalline ZnO films generally contains both a true photoconductivity and a contribution from surface structural changes which can alter the surface conducatance via the chemisorption and photodesorption of an active ambient-gas component. The surface structural changes can increase the conductance by up to seven orders of magnitude for a 500nm thick sample when illuminated with an intensity of 4
