The potential across a pn junction is called potential barrier because majority charge carriers have to overcome this potential before crossing the junction.

Potential barrier is the obstacle created by the depletion layer which prevents majority charge carriers from flowing across the pn junction freely

What is meant by 0.3 volts for germanium and 0.7 volts for silicon?

This refers to the forward voltage drop across a diode made from germanium or silicon. It signifies the voltage level at which the diode starts conducting electricity in the forward direction. Germanium diodes typically have a forward voltage drop of around 0.3 volts, while silicon diodes have a slightly higher drop at around 0.7 volts.


What is a barrier across a highway called?

It is called a roadblock.


What is depletion region in PN junction?

when the p type semi conductor is connected to n type the electrons in n type migrates towards p type to fill the vacancy i.e holes in p type. As a result accepter ions are developed in n type and donor ions in p type which restrict further movement of electrons and holes . this layer of donor and accepter ions at the pn-junction is called depletion region. and across this region a potential is developed which is called barrier potential.


What is thermal voltage?

In semiconductors, the relationship between the flow of electrical current and electrostatic potential across a p-n junction depends on a characteristic voltage called the thermal voltage, denoted VT.


The chemical that transmits the signal across the neuromuscular junction is called?

Acetylcholine is the chemical that transmits signals across the neuromuscular junction. It binds to receptors on the muscle cell membrane, leading to muscle contraction.


What is junction potential?

Junction potential refers to the difference in electrical potential that exists at the interface between two different solutions with different ionic concentrations. It can occur in electrochemical cells and can affect the accuracy of measurements taken in such systems. Special techniques may be required to account for junction potential in order to obtain more accurate results.

When an external battery is placed across a p-n junction what does this process called?

Making a circuit? Sorry, but its not entirely clear from your question what you are asking about. Also depending on battery voltage and polarity, the junction may or may not be destroyed.


What is the junction called between 2 communicating neurons?

The junction between two communicating neurons is called a synapse. At the synapse, electrical signals called action potentials are converted into chemical signals in the form of neurotransmitters, which then travel across the synaptic cleft to relay the signal to the next neuron.


What is the space junction between two neurons called?

The space junction between two neurons is called a synapse. It is a small gap where the electrical signal in the form of an action potential is converted into a chemical signal in the form of neurotransmitters to allow communication between neurons.

The junction between a motor neruon's axon and the muscle cell membrane is called a neuromuscular junction or a myoneuraljunction?


What is the border across which genes can flow between two populations called?

The border across which genes can flow between two populations is called a "gene flow barrier." This barrier can be physical, such as a mountain range or river, or it can be due to behavioral or ecological factors that limit gene exchange between populations.
