Low dimensional material systems provide a unique set of properties usefulfor solid-state devices. The building block of these devices is the PNjunction. In this work, we present a dramatic difference in the electrostaticsof PN junctions in lower dimensional systems, as against the well understoodthree dimensional systems. Reducing the dimensionality increases the depletionwidth significantly. We propose a novel method to derive analytic equations in2D and 1D that considers the impact of neutral regions. The analytical resultsshow an excellent match with both the experimental measurements and numericalsimulations. The square root dependence of the depletion width on the ratio ofdielectric constant and doping in 3D changes to a linear and exponentialdependence for 2D and 1D respectively. This higher sensitivity of 1D PNjunctions to its control parameters can be used towards new sensors.
