Near absolute zero temperature pure semi-conductors behave like:
Correct answer: C. Insulators
- A. Conductors
- B. Metals
- C. Insulators
- D. None of these
Explanation
Near absolute zero temperature, pure semiconductors behave more like insulators. At extremely low temperatures, most of the electrons are bound tightly in the valence band, and very few are able to overcome the energy gap to move into the conduction band. This lack of available electrons in the conduction band results in minimal conductivity, similar to how insulators behave due to the absence of free charge carriers at normal temperatures.

About Electronics
A p-n junction forms when p-type and n-type semiconductor regions meet, creating a depletion layer, barrier potential and rectifying action. The work covers forward and reverse bias, junction current, diode characteristics, and how a diode converts alternating current into pulsating direct current through half-wave and full-wave rectification.
