Organic semiconductors offer a number of benefits over traditional silicon based semiconductors, such as the possibility of flexible and transparent devices. Organic semiconductors can be synthesized from solution in high yields, circumventing the high energetic costs associated with monocrystalline silicon. Major concerns facing organic semiconductors are low and highly variable charge-carrier mobilities, an integral property of semiconducting materials. Previous works have demonstrated a link between low-frequency vibrations and the charge-carrier mobility of a material. The results of this study highlight a new kind of motion, expanding upon upon the known class of vibrational modes detrimental to semiconducting behavior.
