A High-Performance Room-Temperature NO2 Sensor Based on An Ultrathin Heterojunction Film
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. [GRAPHICS] .
