Abstract

original image

A heterojunction device which has good transport characteristics and low sensitivity is obtained through two kinds of organic molecules inert to NO2. Using the heterojunction device, constructing more-sensitive double-heterojunction devices can obtain better room-temperature detection characteristics.
