Photo-response Modulation of Organic Transistors for Multi-level Light Sensing using Active Layer Microstructure Control Dohyeong Park, Gergely Tarsoly, Dongyub Kwon, Tae Joo Shin and Seungmoon Pyo Abstract Annealing processes are widely used to alter the morphology of organic films and optimize the electrical properties of organic field-effect transistors (OFETs). However, the impact of annealing processes on the photo-response characteristics of phototransistors is not widely studied.

Optimizing the photoresponse enhancement in hybrid inorganic-organic phototransistor with an amorphous indium gallium zinc oxide channel layer and PTCDI-C13 photoactive layer Gergely Tarsoly, Jae-Yun Lee, Yong Jin Jeong, Seungmoon Pyo and Sung-Jin Kim Abstract Amorphous metal oxide semiconductors offer high performance and versatility for new generation electronic devices. On the other hand, their applicability to optoelectronics is limited by their wide bandgap.

In-situ PTCDI-aided Lateral Crystallization of Benzothieno-benzothiophene Derivative for Photoresponsive Organic Ambipolar Devices Here, we report a laterally stacked organic crystal active layer formed from the mixed solution of a perylene diimide derivative (PTCDI-C5) and a benzothieno-benzothiophene derivative (C8-BTBT) through a solution process called In-situ PTCDI-aided lateral crystallization, where PTCDI-C5 serves as an n-channel semiconductor as well as a template for the...
