(Yicai Global) June 4 -- A research  team from Shanghai's Fudan University has invented a transistor  structure that may shrink this type of semiconductor devices by 50  percent. The new technology could make electronic gadgets smaller,  lighter, and more powerful.

Researchers  were observing the surface of a silicon wafer. The new invention was  published in Nature Publishing Group's science journal Nature  Nanotechnology.

Transistors are used to amplify or switch electronic signals and electrical power.

Scientists were cleaning a silicon wafer in the lab.
