"device and put it in liquid electrolyte—sodium chloride dissolved in water... drive sodium migrate into CPE-K active layer by applying positive voltage at gate. Alternatively, can change polarity of voltage and drive chloride migrate to active layer... organic doping materials cluster together instead of dispersing... don't run into the issue of uneven dopant distribution. You also avoid the whole process of optimizing the dopant and determining the right mix and proportions, all of which add steps and complicate processing"
