Self-organizing molecular semiconductor. new material of high potential for optoelectronic applications

Recently, a new type of organic semiconductors exhibiting liquid crystallinity have been discovered, i.e., self-organizing molecular semiconductor (SOMS), which meets an essential requirement of large-area uniformity for device applications due to liquid-like fluidity and enjoys enhanced carrier transport properties due to crystal-like molecular alignment. In this talk, the general electrical properties of the SOMS are surveyed in comparison with the conventional amorphous organic semiconductors and discussed how the superior properties are utilized in device applications with the reference to some demonstrated device applications including a high speed photosensor, a xerographic photoreceptor, and a polarized light emitting diode.
