The acceptor level of a p-type semiconductor is
Multiple Choice Options
- A 407 nm
- B 103.5 nm
- C 414 nm
- D 207 nm
Step-by-Step Verified Solution
The energy required to create a hole in a p-type semiconductor can be directly related to the acceptor level because this energy level represents the minimum energy required to excite an electron from the valence band into the acceptor level, effectively creating a hole. The acceptor level is given as
To find the maximum wavelength of light that can excite an electron into this level, we use the equation that relates the energy (
Where:
is the energy in electronvolts (eV), is Planck's constant, is the speed of light, and is the wavelength in nanometers (nm).
The product of
Substituting the given values:
Thus, the maximum wavelength of light that can create a hole in the semiconductor by exciting an electron into the acceptor level is
