What does conduction band represent in forbidden energy gap of pn- junction diode?
In a pn-junction diode, the conduction band represents the range of energy levels that electrons can occupy and move freely, contributing to electrical conductivity. The forbidden energy gap, or band gap, is the energy difference between the conduction band and the valence band, where no electron states exist. In a pn-junction, electrons can be promoted from the valence band to the conduction band, allowing current to flow when the diode is forward-biased. The size of the forbidden energy gap influences the diode's electrical properties and its response to temperature and light.
Why is the diode reverse biased in energy band gap experiment?
In reverse bias,the currents flowing through the junctioare very smalland interal heating of junction does not takes place
In an experiment of finding energy gap of a semi conductor by using diode what is the junction voltage?

What type of membrane junction allows ions to pass directly from cell to cell?
Gap junctions
What is cell to cell junction called?
Gap junction
What is the significance of the optical band gap in the study of semiconductors?
The optical band gap is important in the study of semiconductors because it determines the energy required for electrons to move from the valence band to the conduction band, allowing them to conduct electricity. This gap influences the semiconductor's ability to absorb and emit light, which is crucial for various electronic applications such as solar cells and LEDs.
What are the three types of the cellular junction?
Communication Junction Desmasomes/Anchor Junction Gap Junction
Practical of to determine energy band gap of semiconductor diode by determining variation of saturation current with temperature?
To determine the energy band gap of a semiconductor diode, you can plot the natural log of the saturation current against the inverse of temperature. By analyzing the slope of this plot using the equation for diode current and adjusting for temperature effects, you can calculate the energy band gap. This method is based on the relationship between current density and temperature in semiconductor devices.
What function does gap junction provide?
The main function of a gap junction is to allow the transmission of electrical impulses among cells. These transmissions come from neighboring cells and they would not be able to communicate without a gap junction.
The type of intercellular junction that forms tubular channels is a?
gap junction
What is power diode generally made from?
As that of most power devices power diode are maid from silicon material(because of its wide band gap) . but now days alloy of silicon are used like sic(silicon carbide) by ank
