Researchers have developed a single-atom transistor, the world's smallest. This quantum electronics component switches electrical current by controlled repositioning of a single atom, now also in the ...

In previous parts of this series we reviewed the basic transistor parameters that determine ac voltage gain and practical considerations limiting high gain. The role of a coupling capacitor was ...

A team of engineers has developed a transistor made from linen thread, enabling them to create electronic devices made entirely of thin threads that could be woven into fabric, worn on the skin, or ...
