From: Detecting defects that reduce breakdown voltage using machine learning and optical profilometry

(a) A histogram plot showing the distribution of breakdown voltages for all 3912 diodes in this work. Using the breakdown voltage, the diodes were divided into four categories related to the type of defects present: 0th, 1st, 2nd, and only higher order defects (Good Devices). (b) Example curves from the histogram plot in (a).
