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 ...

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 ...

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 ...

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 ...

Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is ...

During the manufacture of semiconductor wafers, thickness measurement forms an important part of this process, since it provides process engineers with the information required to ensure that ...
