The built-in potential is the potential difference established at the junction of two different materials, such as a p-n junction in a semiconductor device. It arises due to the electrostatic forces that separate the charge carriers across the junction, creating a barrier for the flow of current. This potential is an important parameter in determining the behavior of semiconductor devices.

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 the relationship between potential energy and electric potential?
The relationship between potential energy and electric potential is that electric potential is a measure of the potential energy per unit charge at a specific point in an electric field. In other words, electric potential is the potential energy that a unit charge would have at that point in the field.
Does everything have potential energy?
No, not everything has potential energy. Potential energy is the energy that an object has due to its position or state, such as gravitational potential energy or elastic potential energy. Objects that are stationary or at rest may not have potential energy.
How are potential and kinetic energy related?
Potential and kinetic energy are related in that potential energy is stored energy that can be converted into kinetic energy, which is the energy of motion. When an object has potential energy, it has the potential to move and therefore has the potential to have kinetic energy.
What is the relationship between electric potential, voltage, and the concept of electric potential energy?
Electric potential, also known as voltage, is a measure of the electric potential energy per unit charge at a point in an electric field. The relationship between electric potential, voltage, and electric potential energy is that electric potential is the potential energy per unit charge, and voltage is the difference in electric potential between two points. Electric potential energy is the energy stored in a system of charges due to their positions in an electric field, and it is related to the electric potential by the equation: Electric Potential Energy Charge x Electric Potential.
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.
What is The natural voltage across a semiconductor is called?
The natural voltage across a semiconductor is referred to as the "built-in potential" or "built-in voltage." This voltage is created due to the difference in concentration of charge carriers (electrons and holes) in the p-type and n-type regions of the semiconductor, leading to the formation of a depletion region at the junction. The built-in potential is essential for the operation of semiconductor devices like diodes and transistors, as it influences their electrical characteristics.
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 are forts called that spanish settlers built?
Spanish settlers typically built forts known as 'presidios' in the areas they colonized. These presidios served as military garrisons to protect the settlers and defend against potential threats.
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.
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.
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.
