Effect of annealing temperature on thermoelectric

Fig. 1a shows high symmetry peak of core level of Zn 2p.The binding energy of the Zn 2p 3/2 and Zn 2p 1/2 peaks is loed at 1021.9 and 1044.9 eV, respectively, regardless of various doping elements and thermal treatment. The binding energies of the Ga 2p 3/2 and Ga 2p 1/2 as seen in Fig. 1b are found to be 1118.2 and 1145.1 eV, respectively, for both the GZO and IGZO films.
