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 characteristic...

Summary: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.
