Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
What else can I help you with?
What makes electrons move through a conductor in only one direction?
Electrons move through a conductor in one direction due to the presence of an electric field created by a voltage difference. This field exerts a force on the electrons, causing them to flow in the direction of lower potential. Additionally, the structure of the conductor, such as in a diode or semiconductor material, can allow electrons to move more freely in one direction than the other.
Is germanium a conductor of heat?
Germanium is a semiconductor, it means that electrons are relatively strongly attached to nuclei. As result its thermal properties change. Generally semiconductors have worse thermoconductivity than metals but better than insulators.
What causes electrons to flow through a conductor?
There are 1 to 3 electrons in outer orbit of a conductor witch the element wants to give away in order to have inner orbit complete at the cost of getting positive charge when forced by the electric voltage.If outer orbit have 4 electrons like carbon,silicon or germanium, it acts as a semiconductor. And if outer orbit have more than 5 electrons, it will resist electron flow.
Is water a better conductor than metal?
No, water is not a better conductor than metal. Metal is a much better conductor of electricity than water because of its free-flowing electrons that allow for easier passage of electric current. Water, on the other hand, is a poor conductor of electricity due to its lack of free electrons.
Is germanium good conductor of heat?
Germanium is a semiconductor, it means that electrons are relatively strongly attached to nuclei. As result its thermal properties change. Generally semiconductors have worse thermoconductivity than metals but better than insulators.
How many free electrons in semi-conductor?
A semiconductor typically has fewer free electrons than a conductor but more than an insulator. The number of free electrons in a semiconductor can vary based on factors like doping and temperature, but in general, it is on the order of 10^15 to 10^19 free electrons per cubic centimeter.
Why does a semiconductor have fewer free electron than a conductor?
Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.
Is sodium a semiconductor?
It is a semiconductor.
This alkali metal has 76 fewer electrons than francium?
The alkali metal with 76 fewer electrons than francium is lithium. Francium has 87 electrons, so lithium, which has 3 electrons, has 76 fewer electrons than francium.

Which has greater mobility in intrinsic semiconductor Electrons or holes?
The mobility of electrons is always greater than holes. Only the number of electrons and holes would be same in an intrinsic semiconductor.
Does the boron atom has fewer or more electrons than lithium atom?
The boron atom has fewer electrons than the lithium atom. Lithium has 3 electrons in its neutral state, while boron has 5 electrons.
Does a boron Atom has fewer or greater electrons then lithium?
A boron atom has fewer electrons than a lithium atom. Lithium has 3 electrons while boron has 5 electrons.
What material conducts electric current better than an insulation but not as well as a conductor?
semiconductor
What material conductors electric current better than an insulator but not as well a conductor?
semiconductor
Is germanium a good heat Conductor?
Germanium is a semiconductor, it means that electrons are relatively strongly attached to nuclei. As result its thermal properties change. Generally semiconductors have worse thermoconductivity than metals but better than insulators.
Which atom has 4 fewer electrons than an aluminium atom?
Silicon has 4 fewer electrons than aluminium. Aluminium has 13 electrons, while silicon has 9.
