photoconduction การใช้

• The causes resulting in thickness dependence of the optical properties of the films were discussed on the basis of the pl , optical transmission , and afm analyses . we understood that zno is an excellent material for uv detector by research on uv photoconduction
• At the same time the effection of some important recombinations are discussed and the relation of photoconduction versus time is given . in chapter 4 , auston circuit , blumlein pulse forming line , multiplier of pulse forming line are introduced and give their differentiates
• In chapter 2 , the pcss are manufactured and two technics are introduced . the practical flow is given . meanwhile the linear operational mode and nonlinear operational mode of pcss are analyzed in chapter 3 , after simulating time - space distribution of electron and hole in photoconductor , the relations of laser energy , laser character and photoconduction are analyzed and the fundamental principles of nonlinear phenomenon is introduced
