I’m Somayeh Kashani, a postdoctoral researcher in the Ade Group within the Physics department at NC State. My passion lies in exploring the interdisciplinary realm of organic semiconductors and their diverse applications, ranging from Organic Photovoltaics (OPVs) to organic neuromorphic systems.
What instruments are you using for your research and why do you like them?
I utilize Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) to study the diffusion depth profiles of dopant molecules in organic semiconductor films. This method allows me to understand doping mechanisms and doping efficiency.
What have you been researching?
In my research, I investigate the doping of organic semiconductors and their impact on their electrical properties. This concept is analogous to traditional semiconductor n- or p-doping. Our work aims to enhance the optoelectronic properties of organic semiconductors, paving the way for advancements in various fields. Organic semiconductors offer a range of unique properties. They are easily processed using solution methods and large-area deposition techniques, making them cost-effective for manufacturing. Their opto-electronic properties can be tailored through chemical design. They are flexible, semi-transparent, and biocompatible, enabling diverse applications in flexible electronics, wearable devices, organic light-emitting diodes (OLEDs), and biomedical devices. These qualities make organic semiconductors promising candidates for future technologies. Specifically, these materials are revolutionizing technologies in fields such as energy harvesting, where organic photovoltaics (OPVs) offer lightweight, flexible solar cells for integration into clothing or buildings. Additionally, organic neuromorphic systems are poised to revolutionize artificial intelligence by mimicking the brain’s synaptic functions using organic semiconductor devices.
