PN junction optoelectronic devices:the integration of research innovation and teaching
The innovative development of low-dimensional materials in the field of optoelectronic devices was elaborated,and the undergraduate experimental module with PN junction photodetectors was designed.The photocurrent response of PN junction photodetectors was measured by a photoelec-tric characteristic testing system,and the mechanism of photoresponse was deeply analyzed.With guidance of the teacher,students completed material preparation,device testing and theoretical analy-sis,which not only promote the transformation of research results to undergraduate teaching,but also deepen students'comprehension of fundamental principles associated with PN junctions.
