If the effective mass of holes is greater than the effective mass of electrons in semiconductor material, Question 3 options: the intrinsic Fermi energy is slightly above the center of the bandgap. the bandgap is wider than it would be if the situation were reversed. there is no effect on the intrinsic Fermi energy level. the intrinsic Fermi energy is slightly below the center of the bandgap.

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
