Infrared Photodetectors Based on Low-Dimensional Materials

This book is focused on the study of physical mechanisms and device design for achieving high-performance infrared photodetection based on low-dimensional materials. Through theory analysis, material characterization and photo-electric measurements, it provides solutions to the trade-off problems which are commonly encountered in traditional infrared photodetectors and presents novel methods to improve the responsivity, detectivity and response speed. Researchers and scientists in the field of opto-electronic device can benefit from the book.

Nominated as an outstanding PhD thesis by the University of Chinese Academy of Sciences? Provides a new type of photodetector with hybrid structure to surpass existing limitations in sensitivity Presents reliable experimental methods to develop a multispectral active infrared imaging
