Abstract
【解決手段】2つの平板状電極1及び3と、液晶性有機半導体に強誘電性を付与した強誘電性液晶物質2とを備え、前記平板状電極は前記強誘電体液晶物質を挟み、前記平板状電極間に電圧を加えることにより前記強誘電性液晶物質を分極させ、電荷注入を促進させる液晶性有機半導体素子。
【選択図】図1
Description
図1は、本発明による有機半導体素子の構造を示している。図2は、有機半導体素子として使用したテルフェニール(terphenyl)系の強誘電性液晶物質の分子構造を示している。図3は、電極間距離を1.5μmとした場合の電流電圧特性を示している。
実施例2としては、実施例1と同様の電極材料及び強誘電性液晶材料を使用し、電極間距離を13.5μmと厚くした液晶セルである。電極間距離が13.5μmの液晶セルでは、電圧を印加し、電界を高くしていくと分極により電荷注入が促進され、105V/cm程度から、傾き2の空間電荷制限電流(SCLC)が観測された。
