The state of an electron in 1-D cavity of length 1.0 nm in a semi conductor is described by the normalized wave function Ψ(x)= 1/2Ψ1(x) + [1/(2i)] Ψ2 (x) -(1/2)1/2 Ψ4 (x), where Ψn(x) is given by equation
Ψn (x) = (2/L)1/2sin [(nπx)/L] for 0≤ x ≤ L.
Determine the outcome when the energy of the electron is calculated? Discuss the expectation value of the energy?
