Abstract
▶ Electrical characteristics of the pentacene transistor subjected to a UV light excitation at a wavelength of 365nm were analyzed. ▶ A significant increase in the drain current of the pentacene thin film transistor under a UV excitation of 365nm is observed with a maximum photosensitivity of 4.51 in the depletion regime. ▶ It is evaluated that the pentacene thin film transistor can be used in UV photo-detecting devices.
The pentacene thin film transistor was fabricated on a SiO2/Si substrate by thermal evaporated method at room temperature. Electrical characteristics of the pentacene transistor subjected to a UV light excitation at a wavelength of 365nm were analyzed. A significant increase in the drain current of the pentacene thin film transistor under a UV excitation of 365nm is observed with a maximum photosensitivity of 4.51 in the depletion regime. It is concluded that the pentacene thin film transistor can be used in UV photo-detecting devices.
