Why germanium has less barrier potential than silicon?
germanium has great intrinsic concentration at room temperature,hence conduction is great in germanum compared to silicon, and resistance decreases in germanum and hence built in potentail also less in germanum compared to silicon.built in potential of silicon is 0.7v built in potential of germanum is 0.3v. 1)intrinsic concentration of germanium at room temperature is 2.5*10^13 atoms/cm^3. 2)intrinsic concentration of silicon at room temperature of 300k is 1.5*10^10 atoms/cm^3.
What is meant by 0.3 volts for germanium and 0.7 volts for silicon?
== When we make a semiconductor junction (a p-n junction), the electric fields force charges to shift creating what is called a depletion region. This depletion region forms a potential barrier across the junction. This potential barrier has a voltage associated with it, and that voltage is 0.3 volts (approximately) for germanium semiconductor material, and 0.7 volts (approximately) for silicon semiconductor. The terms we apply to this barrier potential are the built-in voltage (or potential), junction voltage (or potential), and contact potential.

Is a electric potential scalar or vector?
Electric potential is a scalar.
What equation connects both scalar potential and vector potential?
let A be the Vector potential and Q as the scalar potential
What form of potential energy does a person blowing a vuvuzela have?
chemical potential energy
What horse power potential does a fully built K20A R have?
7000 7000
Diffusion potential in p-n junction?
The built in potential in a pn junction. Due to the difference in carrier concentration between the sides of a pn junction. Diffusion potential increases with increase in doping levels.
What cuases electric discharge?
Potential differnce. For example, when too much voltage is built up within a thunderhead, the potential difference is high and a discharge occurs.
Why potential across pn junction is called potential barrier?
The potential across a pn junction is called potential barrier because majority charge carriers have to overcome this potential before crossing the junction.
What energy system are you using when you sit?
Kinetic energy because we have already built up the potential energy by standing.
Can lightning strike anywhere?
Just about. It strikes when the electric potential has built up high enough to ionize the air. That can happen anywhere.
What is thearpy?
It is a personality perspective that emphasizes the individual, personal choice, and free will in shaping personality; assumes that humans have a built-in-drive toward fulfilling their own natural potential.
How built-in potential barrier is formed in an open circuited P-N junction?
depletion layer surrounding the junction where electrons from N side have fallen into holes from P side.
What is humanistic thearpy?
It is a personality perspective that emphasizes the individual, personal choice, and free will in shaping personality; assumes that humans have a built-in-drive toward fulfilling their own natural potential.
What are the risks of Frostwire?
Frostwire has no built-in risk; when downloaded from it's official website, it is free and clean of viruses. When being used, it has the exact same potential for misuse and carelessness as Limewire.
Why are lighthouses in specific locations?
Lighthouses are built in areas of potential danger to warn sailors. They are also used as a navigation aid as each lighthouse's lights flash in a different pattern.
What is potential step from 1 potential to o potential?
1 potential to o potential
