Abstract(in English) | The grain growth of a pentacene thin film, which is a well-known p-type organic semiconductor, is sensitive to underneath materials and deposition temperature. In this paper, the pentacene film deposited at 100oC on a HfO2 bottom-gate insulator, which is one of the most famous high-k materials, was investigated to reduce the operation voltage of OFETs. It was found that the grain size of a pentacene film was increased to 10 um, and it was larger than that on SiO2. Furthermore, a nitrogen-doped LaB6 interfacial layer deposited on an SiO2 gate insulator also increased the grain size of the pentacene film, and the device characteristics of the OFET improved. |
