If enough energy were supplied to a diamond would that allow some of its electrons to transition to a higher energy band and therefore conduct electricity? Just curious.

Yes, supplying enough energy to a diamond could indeed allow some of its electrons to transition to a higher energy band, known as the conduction band. This process is called doping, where impurities are intentionally introduced into a material to alter its electrical properties.

In the case of diamonds, which are typically considered insulators or poor conductors of electricity, the addition of certain impurities can change their behavior and make them conductive. This is achieved through a process called semiconductor doping.

To convert a diamond into a semiconductor or conductor, it is typically doped with elements such as boron or phosphorus. Boron-doped diamonds become p-type semiconductors, while phosphorus-doped diamonds become n-type semiconductors.

Boron-doping introduces an imbalance of positively charged "holes" (places where electrons are missing) in the crystal lattice, which can conduct positive charge. Phosphorus-doping introduces excess negatively charged electrons into the lattice, which can conduct negative charge. Both types of doped diamonds can effectively conduct electricity.

So, in summary, if enough energy is supplied to a diamond and it undergoes appropriate doping, the added impurities can cause a transition of electrons to the conduction band, allowing it to conduct electricity.
