| 英文摘要 | Abstractsnse2 field-effect transistor was fabricated based on exfoliated few-layered snse2 flake, and its electrical and photoelectric properties have been investigated in detail. with the help of a drop of de-ionized (di) water, the snse2 fet can achieve an on/off ratio as high as ~?104 within 1?v bias, which is ever extremely difficult for snse2 due to its ultrahigh carrier density (1018/cm3). moreover, the subthreshold swing and mobility are both improved to ～?62?mv/decade and ~?127?cm2?v?1?s?1 at 300?k, which results from the efficient screening by the liquid dielectric gate. interestingly, the snse2 fet exhibits a gate bias-dependent photoconductivity, in which a competition between the carrier concentration and the mobility under illumination plays a key role in determining the polarity of photoconductivity. |
