Electron hole pair
| Глоссарий по экологии и "зеленой" энергетике |
The result of light of sufficient energy dislodging an electron from its bond in a crystal, which creates a hole. the free electron (negative charge) and the hole (positive charge) are a pair. these pairs are the constituents of electricity.

Sufficient, английский

Electricity, английский
- Электричество
- Energy resulting from the flow of charge particles, such as electrons or ions.
- The movement of electrons (a subatomic particle), produced by a voltage, through a conductor.
- Energy resulting from the flow of charged particles, such as electrons or ions.
- The fl ow of passing charge through a conductor, driven by a difference in voltage between the ends of the conductor. electrical power is generated by work from heat in a gas or steam turbine or from wind, oceans or falling water, or produced directly from sunlight using a photovoltaic device or chemically in a fuel cell. being a current, electricity cannot be stored and requires wires and cables for its transmission (see grid). because electric current fl ows immediately, the demand for electricity must be matched by production in real time.
Constituent, английский
- A substance which forms part of something the chemical constituents of nerve cells
- N составляющая (син. phrase) analysis discontinued ~ разрывная составляющая immediate ~ непосредственно составляющая obligatory ~ обязательная составляющая ultimate ~ конечная составляющая unique ~ единичная составляющая
- Составляющая (часть) ~s of concrete компоненты бетона или бетонной смеси
- A person who is associated with, or who is a member of, a non-profit organization.

Waveform, английский
- The shape of the phase power at a certain frequency and amplitude.
- A graph of an audio signal`s sound pressure or voltage over time. the waveform of a pure tone is a sine wave.
Load resistance, английский
- The resistance presented by the load. see also resistance.
- The resistance presented by the load. see resistance.
