What is a N-type material?
An N-type material is a type of semiconductor where silicon or germanium is doped with impurities such as phosphorus or arsenic to introduce free electrons into the material. These extra electrons give the material a negative electron charge, hence the "N" designation. N-type materials are commonly used in electronic devices like transistors and diodes.
What is an electron trap?
An electron trap is a localized region in a material where electrons can be captured and temporarily held. This could be due to defects in the crystal structure, impurities, or other factors that create an energy level in which electrons can get stuck. Electrons trapped in these regions can affect the material's electronic properties.
How many valance electrons does a semiconductor have?
It is not the number of valence electrons that an insulator has that is important. It is the way the valence electrons are "arranged" in the structure of the material that matters. If not all the valence electrons of a substance are "involved" in the structure of the material, then these electrons are said to be free electrons. They move about in the substance, and are free to contribute to electron flow. The metals are examples. In contrast with this, if all the electrons are bound up in a material, they are not free to support current flow, and the material is said to be an insulator. Said another way, if the valence electrons in a material are in a Fermi energy level that overlaps the conduction band for that material, the material is a conductor. In an insulator, the valence electrons are all in Fermi energy levels that are below the conduction band for that material, and it is an insulator. Applying a voltage to an insulator will not "lift" the valence electrons up into the conduction band to allow them to support current flow.
What type of material allows electrons to move freely?
Electrons move freely in a solid, as in a metal
Why do materials with extra electrons often stick to a material with missing electrons?
The electrostatic force attracts the opposite charges.
How difficult is it for electrons to flow through a material?
Electrons 'jump' from one atom to another. The electron configuration of the atoms determine how easy it is for an electron to move from one atom to another, which is a factor in determining conductivity of the substance.Actually in atoms in the solid state, electrons occupy one of 2 quantum energy bands: the valence band or the conduction band. Valence band electrons are tightly bound to the atom, but conduction band electrons are not bound to the atom and can roam freely through the material.insulators have very few if any conduction band electrons and thus cannot conductconductors have so many conduction band electrons that they form what is called an electron gas that fills all of the material and can flow freely, there is no"'jumping' from one atom to another" at all
Why solid materials did not change their characteristic when you mixed to other solid material?
There are a few reactions wich happen between two solids. but the reason most reactions wont work between two solids is because the electrons aren't free enough to move.
Which reactions require oxygen as a raw material 1 light reactions only 2 dark reactions only 3 both light and dark reactions 4 niether light or dark reactions?
Neither, oxygen is a byproduct, not a reactant or "raw material."
What material keeps electrons from moving?
This is called an insulator material.
Electrons do not readily flow through what material?
Electrons do not readily flow through insulating materials, which have a high resistance to the flow of electric current due to their tightly bound electrons. Examples of insulating materials include rubber, plastic, and glass.
How friction can be used to transfer electrons?
Friction can transfer electrons by causing the rubbing of materials together, which results in the transfer of electrons from one material to another. This transfer occurs due to the buildup of electrostatic charges on the surface of the materials, leading to the movement of electrons from one material to the other.

What is the series of enzyme-controlled reactions that build complex material from simple material?
Anabolism
Why silicon is used in zener diode?
silicon is used in (almost) every electronic device. silicon has four valence electrons. Molecules tend to want four valence electrons, so elements with three valence electrons (P-type material) want to steal one from other elements, and elements with five valence electrons (N-type material) want to give one away. P-type and N-type materials are mixed in electronic circuits to create transistors, diodes, etc. Silicon is used as an unbiased foundation for layering these N-type and P-type materials to create circuits.
What principle can be applied to all chemical reactions?
The principle of conservation of mass can be applied to all chemical reactions. It states that the total mass of the reactants must equal the total mass of the products, as no atoms are created or destroyed during a chemical reaction.
What is the rubbing force that strips electrons or a material and makes it charged?
The rubbing force that strips electrons or a material and makes it charged is friction!i
What is the ability of a material to oppose the movement of electrons through it?
A material that has a high resistance to the flow of electrons is an insulator.
