    摘要: A field-effect transistor includes a source region; a drain region; a semiconductor layer disposed between the source and drain regions; a gate region; and a dielectric region disposed between the semiconductor layer and the gate region. The semiconductor layer comprises a titanium dioxide film. The transistor may be light sending, gas- or bio-sensing, or used in a visual display or in electronic circuits. The transistor is formed by forming a dielectric layer adjacent a gate region; forming a source region and a drain region; and forming a semiconductor layer on the dielectric layer, the semiconductor layer comprising titanium dioxide. The titanium dioxide semiconductor layer may be deposited by spray pyrolysis, or alternatively mesoporous TiO2 films of nanocrystalline morphology may be formed by spin coating, doctor-blading or screen-printing techniques.

    摘要: A low-voltage thin-film field-effect transistor is formed by forming a gate, forming a dielectric layer on the surface of the gate, forming a source region and a drain region, and forming a semiconductor layer adjacent the dielectric layer. The dielectric layer is formed as a native oxide layer by oxidizing the surface of the gate. The semiconductor layer is deposited by spray pyrolysis. The dielectric layer may be functionalized with a self-assembling monolayer dielectric layer. The dielectric layer may be formed as a self-assembling monolayer, without first forming a native oxide (or other) dielectric layer.
