Structural and Electrical Studies on ZnO-Based Thin Films by Laser Irradiation

Table 2

The characteristic parameters of grain-boundary of ZnO-based ceramic films before and after laser-irradiation processing.

State	Barrier height; (eV)	Barrier width; (Å)	Donor concentration; (10^22 cm^−3)	Density of interface states (10^14 cm^−2)
Before irradiation (I)	1.86	1.13	13.5	15.3
After irradiation (II)	2.41	0.31	227	71.6
