Semiconductive materials do not conduct current well because their valence band is mostly filled and their conduction band is mostly empty, requiring an input of energy for electrons to move from the valence to the conduction band and thus carry a current. Additionally, semiconductors have a wider band gap compared to conductors, which further restricts the flow of electrons.
What else can I help you with?
Why don't semiconductive materials conduct current well and are of little value in their intrinsic state?
Semiconductive materials have a wider band gap compared to conductive materials, which requires more energy to move electrons into the conduction band. This results in poor conductivity in their intrinsic state. However, by introducing impurities or doping, their conductivity can be enhanced, making them valuable for use in electronic devices.
What are ALL the materials that can conduct electricity?
Some materials that can conduct electricity include metals such as copper, silver, and aluminum, as well as carbon in the form of graphite. Conductivity is based on the availability of free electrons within the material to carry electric current.
What does not conduct electricity well?
I think it could be lead
What is the ability to transmit electrical currents called?
The ability to transmit electrical currents is called conductivity. Materials that conduct electricity well are known as conductors, while those that do not conduct electricity are known as insulators.
Comparing density and conductivity?
Density and conductivity are two distinct physical properties of materials. Density measures how much mass is contained in a given volume, reflecting how tightly packed the particles are within a substance. Conductivity, on the other hand, refers to a material's ability to conduct electric current or heat, which depends on the mobility of charge carriers or thermal energy transfer. While dense materials can sometimes be good conductors (like metals), this is not a strict correlation, as some dense materials may not conduct electricity well, and some less dense materials can be excellent conductors.

Why semi conductive materials do not conduct current well and are og little value in their instrinsic state?
why semi conductive materials do not conduct current well & all of little value in their intrinsic state
What do you call materials that do not conduct eletricity well?
Materials that do not conduct electricity well are called insulators. These materials have high resistance to the flow of electrical current, preventing the movement of electric charge through them. Examples of insulators include rubber, glass, and plastic.
What type of materials do not conduct as well as metals do?
Materials such as rubber, wood, plastic, and glass do not conduct electricity as well as metals do. These materials have high electrical resistance compared to metals, which allows for minimal to no flow of electric current through them.
Do all electrical conductors conduct current equally well?
No, not all electrical conductors conduct current equally well. The ability of a material to conduct electricity is determined by its conductivity, which can vary depending on factors such as the material's composition, structure, and temperature. Metals like copper and silver are known for their high conductivity, while materials like plastic and rubber have low conductivity.
Does metal conduct heat well?
yes. metals conduct heat and electric current well.
What materials conduct heat well or poorly?
Materials that conduct heat well include metals such as copper and aluminum, as well as materials like graphite and carbon steel. Materials that conduct heat poorly include wood, rubber, and plastic, as they have low thermal conductivity. insulating materials like foam and fiberglass also have poor heat conduction properties.
Why do some materials conduct electricity?
For a material to conduct electricity , it has to be impure , so for example pure silicon cannot conduct electricity but Silicon chips in computers that are mixed with other things can. So the materials that conduct are charged with little particles that allow the flow of electricityBecause of electrolytes. Or because of the metal something is made of.
What are ALL the materials that can conduct electricity?
Some materials that can conduct electricity include metals such as copper, silver, and aluminum, as well as carbon in the form of graphite. Conductivity is based on the availability of free electrons within the material to carry electric current.
Does not conduct electricity well?
Materials that do not conduct electricity well are Insulating materials, or insulators. Examples include glass, rubber, plastic, air, ceramic, porcelain, dry paper and dry wood. Pure water will not conduct electricity at all.
Is paper bag a insulator or a conductor?
It is an insulator, most metals can conduct paper doesn't conduct..
What are some materials that conduct?
Some materials that conduct electricity include metals like copper, silver, and gold, as well as carbon in the form of graphite. In addition, solutions containing ions, like saltwater, can also conduct electricity.
