- The same kind of semiconducting material used to make an LED can also be used to convert absorbed light into electric energy, essentially operating as an LED in reverse. In this case, the absorption of a photon causes an electron transition from a filled state in the valence band to an unfilled state in the conduction band. If ΔEband = 1.4 eV, what is the minimum wavelength of electromagnetic radiation that could lead to electric energy output?A. 140 nm B. 890 nmC. 1400 nm D. 8900 nm4. Liner ionic crystal.

Show that the work done in a compressing a unit length of the crystal has the leading term C8²/2, where 2 (n-1)q² In 2 (CGS) C = U(R): = 2Nq² In 2 (₁-1). Ro n Ro To obtain the results in SI, replace q² by q²/4л. Note: We should not expect to obtain this result from the expression for U(R), but we must use the complete expression for U(R).SOLID STATE physics
