Engineered crystals for transistors (IMAGE) University of California - Berkeley Caption University of California, Berkeley, engineers have created engineered crystal structures that display an unusual physical phenomenon known as negative capacitance. Incorporating this material into advanced silicon transistors could make computers more energy efficient.
