Transforming Transistors With Liquid Nanotechnology

Transistor fabrication is a highly complex process, requiring high-temperature, high-vacuum equipment. In another step in combining consumer electronics and nanotechnology, University of Pennsylvania engineers have shown a new approach for making transistors: sequentially depositing their components in the form of liquid nano-crystal inks. The researchers’ nano-crystal-based field effect transistors were patterned onto flexible plastic backings using spin coating but could eventually be constructed by additive manufacturing systems, like 3-D printers.
