The cover identifies the Part C major option, Trinity Term 2019, 17 June 2019, A11046W1; the bundle's 2018 filename does not determine the examination year. All six questions are treated. Figure 2(A) has missing image tiles, including part of its lower-left plot and some path labels. The readable portions and the standard silicon valley model support the conclusions below; the missing image content is not reconstructed. Numerical values read from plotted curves are estimates. Write $e>0$ for the elementary electric charge.

TODO: Recover the missing tiles of original Figure 2(A), affecting questions 2(a) and 2(e). The solutions distinguish the surviving figure and standard silicon-band interpretation from unavailable path labels and precise missing valence-sheet contours.
