(A) The statement "At absolute zero degrees Kelvin temperature, semiconductor materials behave as insulators" is true. At absolute zero temperature, the electrons in the valence band of a semiconductor have very low energy and are tightly bound to their atoms, making it difficult for them to move and carry electric current. As a result, semiconductors act more like insulators at absolute zero.
(R) The statement "At absolute zero degrees Kelvin temperature, there is no energy available to generate the current carriers in the semiconductor" is also true. At absolute zero, the temperature is at its minimum possible value, and the thermal energy of the semiconductor is essentially zero. Without thermal energy, there is no energy available to promote electrons to higher energy levels and create mobile charge carriers, such as electrons and holes, which are necessary for conduction in semiconductors.
The explanation (R) provides a correct reason for why statement (A) is true. At absolute zero, the absence of energy to generate mobile charge carriers is why semiconductor materials behave as insulators.
Therefore, the correct answer is A: Both A and R are true, and R is a correct explanation of A.
