some semiconductors have comparatively low resistivity, and this is due to their containing electrically active impurities with energy-levels near a band edge. Others have very high resistivity and this is due to their containing a predominance of impurities with levels far from the band edges, that is, far compared with the thermal energy kT. These latter materials are often referred to as insulators, but since they can carry electronic currents we prefer to introduce the term 'semi-insulator' to describe them.

What is the difference between insulator and bad conductor and semi conductor?
Insulator: A material that does not allow the flow of electricity. Bad conductor: A material that has a low conductivity compared to good conductors but can still allow some flow of electricity. Semiconductor: A material that has conductivity between that of insulators and conductors, and its conductivity can be controlled by factors like temperature or impurities.
Is lead conductor semi conductor or insulator?
Lead is a metal and is considered a good conductor of electricity. It is not a semiconductor or insulator.
Is cotton an insulator or a conductor?
semi conductor
IS PERSPEX A SEMI CONDUCTOR?
No, Perspex is not a semiconductor. It is a type of transparent plastic material known as polymethyl methacrylate (PMMA). Semiconductors are materials that have conductivity between that of a conductor and an insulator.
Is glass a conductor a semi-conductor or insulator?
Glass is an insulator. It does not conduct electricity because its structure lacks free electrons that can move easily to carry an electric current.
Is copper a conductor insulator or semi conductor?
Copper is a conductor.
Is sodium a semi conductor?
No, sodium is a metal and is not a semiconductor. Semiconductors are materials that have conductivity between that of a conductor and an insulator. Sodium is a good conductor of electricity due to its metallic properties.
Differentiate in between conductor and semiconductor and insulators using band diagram?
Conductor-one which conducts(allow current)electric city in all condition. Semiconductor-One which behaves like conductor as well as insulator depending on condition. Insulator-one which donot conduct(allow current)electric city in all condition

What are semi insulators?
A semi conductor is not a good conductor or a good insulator.
Is lead conductor semi conductor or insulator?

semi conductor
IS PERSPEX A SEMI CONDUCTOR?

What is the difference between an electronics and semi conductor?
Electronics refers to anything that requires electricity to run. A semi conductor is a material that has some properties of a conductor, meaning it allows electricity to flow through it well and some properties of an insulator, meaning it does not allow the flow of electricity through it well. Semi conductors are used extensivly in modern electronics and circuit boards. the queastion makes no sense - check what you are asking
Which element is a semi-conductor of electricity?
Most conductors conduct both heat and electricity well. A semiconductor is a conductor whose resistance is between that of a conductor and an insulator. An example of a semiconductor is silicon which is used in electronic appliances
Is glass a conductor a semi-conductor or insulator?
Glass is an insulator. It does not conduct electricity because its structure lacks free electrons that can move easily to carry an electric current.
What is semiconductor material?
Semi-conductor is a material in which the energy band gap between the conduction band and valance energy band is very less (around 1V) which is in between conductors and insulators So, with just a an excitation energy of around 1v changes the state of semi-conductor to wither conductor or insulator .
