Effect of electrode materials and annealing on metal-semiconductor contact of Ga2O3 with metal

Gallium oxide(Ga2O3) thin films were prepared on Si substrate by magnetron sputtering. The obtained samples were comprehensively characterized by X-ray photoelectron spectroscopy(XPS) and scanning electron microscope(SEM). Ti, Pt, Ni and AZO were deposited on the Ga2O3 thin films as electrodes. This paper mainly studies the metal-semiconductor contact formed by these four materials on the films and the influence of annealing at 500℃ on the metal-semiconductor contact. The I-V characteristics show a good linear relationship, which indicates ohmic contact between Ga2O3 and other electrodes.     

汽车人,变形出发

“几百万年以前,在一个名叫赛普特恩的星球上存在着智慧生命。但他们不是我们所熟悉的生命形态。在星球居住着有思维和感情的智慧机械体—变形金刚。变形金刚分为汽车人和霸天虎。残忍的霸天虎们惟一的目标就是彻底统治宇宙,他们计划要消灭热爱和平的汽车人。一场正与邪的战斗席卷了整个赛普特恩,丰富的资源几近匮乏。汽车人们在这性命攸关的时刻勇敢地选择为生存而战。”—《变形金刚》
