Why do natural diamonds do not behave as semi-conductors?State the Miller indices of the planes that intersect the crystallographic axes at the distances (−a, 2b, −c) and (a, 4b, −4c).State the Miller indices of the planes that intersect the crystallographic axes at the distances (2a, 3b, 2c) and (2a, 2b, ∞c).
- Calculate the planer density of planes (0:-1:-1) for BCC, and FCC crystal structures?Using a simple infinite barrier approximation, calculate the “effective bandgap” of a 10 nm GaAs/AlGaAs quantum well grown along [001] direction. If there is a one-monolayer fluctuation in the well size, how much will the effective bandgap change? This example gives an idea of how stringent the control has to be in order to exploit heterostructures.Use the Jablonski diagram to explain why the narrower the band-gap is, the lower the fluorescence efficiency(fluorescence quantum efficiency) in general.
