These include a wide range of unipolar transistors, which are an essential component of modern electronic systems. Unipolar transistors are field-effect transistors (FETs) that use a single type of ...

Ingots are sliced into wafers just a few millimeters thick, lapped and polished to a flawless mirror shine, and then etched with functional patterns (such as resistors, transistors, and capacitors ...

Researchers at Leipzig University have developed a new process for reversing the polarity of chemical compounds, also known as umpolung, for the precise synthesis of pharmaceuticals. "This ...

The polar vortex, a swirling mass of cold air located over the polar regions, is responsible for the cold. It's bringing extreme cold as far as the Deep South. Overnight lows will be well below ...
