The nanoscale ordering amongst the constituent molecules plays a crucial role in determining the electronic, optical, and photovoltaic properties of organic semiconductors [1]. Understanding of the molecular ordering requires characterization methods that can precisely reveal the details of the ordering. In some cases, such as in TFT-LCD, where the degree of ordering is extremely high and the molecules are almost uniformly semi-crystalline, a large area diffraction technique (e.g. X-ray… CONTINUE READING
