In a semiconductor energy gap between the impurites level and conduction band is 1 me V is it an n type or p type of semiconductor

Explanation

To determine whether the given semiconductor is n-type or p-type based on the energy gap between the impurity level and the conduction band, we can follow these steps:

### Step 1: Understand the Energy Levels
In semiconductors, the conduction band is the range of energy levels where electrons can move freely, contributing to electrical conductivity. The valence band is where electrons are bound to atoms. When impurities are added to a semiconductor, they introduce additional energy levels.

### Step 2: Identify the Impurity Levels
For n-type semiconductors, donor impurities (like phosphorus in silicon) create energy levels just below the conduction band. The energy gap between these donor levels and the conduction band is typically small, around 0.05 eV.
