Synthetic methods produce colloidal nanocrystals that are metallic, semiconducting, and insulating. These nanocrystals have been typically used to form only a single component in devices.
IRG-4 has exploited the library of colloidal nanocrystals and designed the materials, surfaces, and interfaces to construct all the components of field-effect transistors.
The transistors are fabricated from solution over large areas and on flexible plastics and have excellent electrical performance.
