Researchers Create Semiconductor ‘Nano-Shish-Kebabs’ With Potential for 3-D Technologies

Researchers at North Carolina State University have developed a new type of nanoscale structure that resembles a “nano-shish-kebab,” consisting of multiple two-dimensional nanosheets that appear to be impaled upon a one-dimensional nanowire. However, the nanowire and nanosheets are actually a … Continue reading
