Which of the following is the best conductor of electricity?

The energy band gap of gallium arsenide phosphate is $1.98 e\mathrm{V}$. Calculate the wavelength of electromagnetic radiation emitted (in Angstrom), when electrons and holes combine in this alloy semiconductor directly. (Take Planck's constant $\left(h\right)=6.62\times {10}^{-34 }\mathrm{J} \mathrm{s}$)

The mobility of free electrons is greater than that of free holes because

The forbidden gap in the energy bands of germanium at room temperature is about 

If the energy of a photon of sodium light $(\mathrm{\lambda }=589 \mathrm{n}\mathrm{m})$ is equal to the bandgap of a semiconductor, calculate the minimum energy required to create hole-electron pair. Take, $h=6.6\times {10}^{-34} \mathrm{J} \mathrm{s}, c=3\times {10}^8 \mathrm{m} {\mathrm{s}}^{-1}$.
