5c. Yоu hаve gоld оn p-doped GаAs on two different sаmples samples: Sample 1 with a known depletion width (WD1), built in voltage (VBi1), and carrier concentration (holes) NA1. Sample 2 has a 4x increase in hole concentration (NA2 = 4 NA1) resulting in new, known built in voltage VBi2. (a) Is VBi2 larger or smaller than VBi1? (b) Determine the depletion width in the second sample (WD2) in terms of WD1, VBi1, and VBi2.
