This summer, I worked on a research project optimizing the performance of organic field effect transistors (OFETs). The field effect transistor is a major component of modern electronics and circuitry. In particular, the OFET is a type of field effect transistor made up of a polymer or organic small molecule. Interest in OFETs within the energy and scientific communities has piqued over the last few decades due to their low cost, easy processability, and potential for a variety of applications, such as large-scale displays. Throughout the summer, I investigated various methods to control and direct the crystallization process within the channel region of the transistors, which is important since controlling crystallization can help optimize the electrical output and conductivity of the transistor and thus lead to high performance. By the end of the summer, I gained skills relevant to the fabrication of OFETs, was able to extend materials science concepts I had learned in the classroom, and learned the importance of making the best of both every failure and success. My summer research helped cement my passion for and interest in materials engineering in the energy sector, and I am excited for what the future has in store.
