Q. 62 A one-dimensional nanowire has a linear electron density of $10^{8}$ electrons $\mathrm{cm}^{-1}$. The Fermi energy of the system is (in $\mathrm{eV}$ ) (rounded off to two decimal places)
Given: $\frac{\hbar^{2}}{2 m}=0.24(\mathrm{eV})^{2} \mathrm{~s}^{2} \mathrm{~kg}^{-1}$ where ' $m$ ' is the mass of an electron
