A Performance Evaluation of Organic Transistor Materials

"The purity of materials" is an important factor directly influencing their organic field-effect transistor (OFET) device parameters. To check and enhance the quality and purity of the transistor materials, TCI has already started the fabrication and evaluation of the OFET devices using our products. We constantly seek to improve our technology and skill in order to provide high-purity and quality materials.

Purification via sublimation and Comparison of FET performances: Pentacene [P2524] <New!>

We demonstrated the fabrication and evaluation of OFET devices by using high-purity pentacene(99.999%) [P2524] and other companies’ pentacene samples. P2524-based FET devices showed high performance with hole carrier mobilities of 0.39 cm2/Vs (bare substrate) and 1.52 cm2/Vs (OTS-treated substrate).
