Question
The energy required by an electron to jump the forbidden band in silicon at room temperature is about ______.
Options
0.01 eV
0.05 eV
0.7 eV
1.1 eV
Solution
The energy required by an electron to jump the forbidden band in silicon at room temperature is about 1.1 eV.
Explanation:
For pure Si, the band gap or forbidden gap is 1.1 eV. An electron must therefore have this much energy to jump the forbidden band in Si at room temperature.
