... 2) Electrical test method using high density plasmas for high-end printed circuit boards Rev. Sci. Instrum. 83, 013503 (2012) Additional information on J. Appl. Phys. FIG. 3. (Color online) (a) PC1D models (dashed lines) and data (solid lines) for III-V with varying V t and V a . Traces have been staggered vertically. The distortion is removed by using a lower value of V t . (b) For all values of V t , the metallurgical junction location, depletion width, and its change (DW) with V a can be easily observed in dS/dx.
