It is known that an electron with effective mass (m=0.2m0) is inside a practically infinite potential well of 14 nm in width. What is the energy of its first bound state in units of eV? Hint: Calculate in Joules and divide by q=1.6e^-19 to convert to eV. You may assume of h=6.626 x 10^-34 J.s or h=1.055x10^-34 J.s/rad and m0=9.11x10^-31 kg.
