The capacitance of a classical conductor is determined solely by its geometry. When charged, the electrons distribute in space in a manner that minimizes their electrostatic energy. Quantum mechanics ...

The electron transport properties of graphene devices are critical to many applications, but our understanding of these properties is still incomplete, in spite of rapid advances in recent years. One ...

We discussed in the previous tutorials the dielectric—the insulating material that prevents the two parallel conductive plates from touching each other. An electrical current flows when a voltage is ...

Capacitive sensors are found in a wide range of equipment, from consumer electronics to industrial/process control. Touch buttons are increasingly found in lamps and dimmers. Motion detectors can ...
