Abstract: front page image
(EN)The present invention relates to an organic thin film transistor which includes an organic layer comprising an organic compound facilitating the ohmic contact between a semi-conducting layer and electrodes and serving as the semi-conducting layer. The organic thin film transistor according to the present invention has excellent electric contact between the semiconductor layer and the source electrode/drain electrode, and thus can be widely used as components for electric/electronic devices. As a result, as the materials for the source electrode or the drain electrode in the organic thin film transistor, materials which are less expensive and excellent in processibility though they have a low work function as the materials can be used.
(FR)La présente invention concerne un transistor à film mince organique qui renferme une couche organique contenant un composé organique qui facilite le contact ohmique entre une couche semi-conductrice et des électrodes et qui agit comme la couche semi-conductrice. Ce transistor à film mince organique possède un contact électrique excellent entre la couche semi-conductrice et l'électrode source/l'électrode drain, et il peut, donc, être largement utilisé en tant que composants de dispositifs électriques/électroniques. Par conséquent, on peut utiliser, comme matières pour électrode source ou électrode drain dans ce transistor, des matières moins coûteuses et à excellente faculté de mise en oeuvre, bien qu'elles présentent un faible travail d'extraction comme lesdites matières.
