A newly discovered silicone variant is a semiconductor, University of Michigan researchers have discovered—upending assumptions that the material class is exclusively insulating.
“The material opens up the opportunity for new types of flat-panel displays, flexible photovoltaics, wearable sensors or even clothing that can display different patterns or images,” said Richard Laine, U-M professor of materials science and engineering and macromolecular science and engineering and corresponding author of the study recently published in Macromolecular Rapid Communications.
Silicone oils and rubbers—polysiloxanes and silsesquioxanes—are traditionally insulating materials, meaning they resist the flow of electricity or heat. Their water-resistant properties make them useful in biomedical devices, sealants, electronic coatings and more.
