Abstract
null null Regarding sensing properties, a well-accepted theory is that the dielectric constant plays a crucial role in the depletion layer width and sensing response. Nevertheless, this theory has not yet been experimentally well demonstrated and applied in the design of high-performance sensors due to the incompatibility in conductivity, because traditional dielectrics are insulating while sensors are semiconducting. Herein, a very promising...
