Title: METHOD FOR PRODUCING A SEMICONDUCTOR OR CONDUCTIR MATERIAL, AND USE THEREOF
Abstract:
The invention relates to a method for producing a semiconductor or conductor material from a two-dimensionally layered structured base material by means of electrolytic exfoliation in an electrolysis cell, comprising at least one electrode pair made of a first and second electrode, and an electrolyte solution containing at least one dissolved salt and/or sulphuric acid, wherein at least one of the electrodes of the electrode pair contains the two-dimensionally layered structured base material, wherein the salt is chosen from tetraalkylammonium salts, and wherein, during the electrolysis, the polarity of the first and second electrode is reversed periodically, wherein the reversal of the polarity of the electrodes is carried out by applying an alternating current.
