The acceptor level of a \(p\) -type semiconductor is \(6\,eV.\) The maximum wavelength of light which can create a hole would be (Given \(hc = 1242\,eV\,nm)\)
1 \(407\,nm\)
2 \(207\,nm\)
3 \(10.3.5\,nm\)
4 \(414\,nm\)
Explanation:
\(E = 6\,eV\) \(\lambda=\dfrac{h c}{E}\) or \(\lambda=\dfrac{1242}{E(\text { in } e V)} n m\) \( \Rightarrow \lambda = \frac{{1242}}{6}\;nm = 207\;nm\)
