The Japan Society of Applied Physics

The Japan Society of Applied Physics (JSAP) serves as an academic interface between science and engineering and an interactive platform for academia and the industry. JSAP is a "conduit" for the transfer of fundamental concepts to the industry for development and technological applications.

JSAP was established as an official academic society in 1946, and since then, it has been one of the leading academic societies in Japan. The society's interests cover a broad variety of scientific and technological fields, and JSAP continues to explore state-of-the-art and interdisciplinary topics.

To this end, the JSAP holds annual conferences; publishes scientific journals; actively sponsors events, symposia, and festivals related to science education; and compiles information related to state-of-the-art technology for the public.

Abstract

An ambipolar light-emitting organic field-effect transistor (LE-OFET) based on a 1,4-Bis(4-methylstyryl)benzene (BSB-Me) single crystal was developed. The BSB-Me single crystal has very high photoluminescence quantum efficiency (ΦPL) of 89±2%, while ΦPL of the BSB-Me vapor-deposited film is limited to a much lower value of 54±2%. Ambipolar operation with successive blue electroluminescence from the FETs based on the BSB-Me single crystals was demonstrated by realizing nearly equal electron and hole mobilities [about 0.005 cm2/(V s)] with asymmetric gold–calcium contacts. Since BSB-Me single crystals can perform light amplification, the BSB-Me-based ambipolar LE-OFET is a promising candidate for future electrically driven organic blue-emitting solid-state lasers.
