Which of the following is a characteristic of a semiconductor? (2023)
Step 1: Understand what a semiconductor is. A semiconductor is a material that can conduct electricity under certain conditions.
Step 2: Learn about conductivity. Conductivity is the ability of a material to allow electric current to pass through it.
Step 3: Know about absolute zero. Absolute zero is the lowest possible temperature, where all molecular motion stops, which is 0 Kelvin or -273.15 degrees Celsius.
Step 4: Recognize that at absolute zero, semiconductors do not conduct electricity at all. This means their conductivity is zero.
Step 5: Understand that as the temperature increases, semiconductors start to conduct electricity better. This means their conductivity increases with temperature.
