As a very rough approximation, an electron in a quantum dot can be thought of as an electron in a 3D box. By analogy to the 2D box, write down an expression for the energy levels for an electron in a 3D box (write an expression for the special case of a cubic box, with all sides having a length L)

An electron is confined inside a quantum dot, which for this question can be approximated as a one-dimensional quantum box with rigid walls. The ground state has an energy of 0.042 eV. (a) In your own words, explain why the energy of the ground state of the system is larger than zero. (b) Calculate the length of the quantum dot. (c) What wavelength of photon is needed to cause a transition to the next excited state? (d) Is the wavelength...

To a rough approximation, the Earth can be treated as a greybody sphere with uniform temperature, absorptance ? = 0.70 and emissivity ? = 0.61. The low absorptance is largely due to reflection of the incoming sunlight by clouds and ice, while the low emissivity is largely due to greenhouse gases in the atmosphere. a) Over timescales of decades, the total solar irradiance at the Earth varies between about 1360.3 W/m2 and 1362.0 W/m2 . Using the greybody Earth approximation,...

For an electron oscillating around a nucleus, where the oscillation can be thought of as a mass m attached with a spring, a) Write down the equation of motion for an electron oscillating in an applied electric field, assume no damping. Use the formalism developed at the end of Chapter 2 in Silfvast. b) Using oscillatory solutions for the motion as well as the electric field solve for the amplitude of the motion of the electron as a function of...
