Solid state physics
|
Solid-state physics, the largest branch of condensed matter physics, is the study of rigid matter, or solids.
|
Subatomic particles
|
A subatomic particle is a particle smaller than an atom: it may be elementary or composite.
|
N-type doping
|
An N-type semiconductor is obtained by carrying out a process of doping, that is adding a certain type of atoms to the semiconductor in order to increase the number of free negative charge carriers.
|
P-type doping
|
A P-type semiconductor is obtained by carrying out a process of doping, that is adding a certain type of atoms to the semiconductor in order to increase the number of free positive charge carriers.
|
Valence band
|
The valence band is the highest range of electron energies where electrons are normally present at zero temperature.
|
Electronics
|
The field of electronics is the study and use of electronic devices that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors.
|
Faraday's law
|
A practical automotive example of Faradays law is contained in automotive ignition systems which use an induction coil, to step up the nominal battery voltage of 12 volts to the voltage needed to bridge the gap across the spark plug electrodes.
|
PZT
|
Lead zirconium titanate (PZT, also Lead zirconate titanate) is a ceramic material that shows a marked piezoelectric effect.
|
Stepper motor
|
A stepper motor is a type of electric motor that is used when something has to be positioned very precisely or rotated by an exact angle.
|
Tolerances
|
Tolerance in engineering is an allowance made for imperfections in a manufactured object.
|
| Transformer |
A transformer is an electrical device that transfers energy from one electrical circuit to another by magnetic coupling without moving parts. |
