3. a) For a nanocrystalline sample containing particles of unknown size, you measure a band gap energy of 3.65x10 9 Use the plot and the equation of the best-fit line (below) to calculate the particle size (in nm) of this unknown sample. Be sure to show your calculation. (Note: "E" in the plot represents 10^) b) What is the band gap of the bulk material?
