In a world first, researchers at Nagoya University in Japan have successfully developed a resonant tunnel diode (RTD) that operates at room temperature made entirely from Group IV semiconductor ...

Transistors, the building blocks of modern electronics, are typically made of silicon. Because it's a semiconductor, this material can control the flow of electricity in a circuit. But silicon has ...

Atomic Force Microscopy (AFM) showed that stepped terrace structures dominated at low doping levels, while increasing silicon ...

Negative differential resistance, sometimes called negative dynamic resistance (NDR), occurs when an increase in voltage ...

Shibayama and his colleagues have now discovered how to use only Group IV materials to produce a p-RTD that functions at room ...
