Fabricating microelectronic devices for two-dimensional (2D) materials research is essential but often limited by the high cost and need for specialized facilities. This study presents an efficient and sustainable method for cleaning and reusing substrates with pre-patterned electrodes. The cleaning protocol involves the use of an ultrasonic bath in warm N-methyl-2-pyrrolidone (NMP), enabling the removal of 2D materials without damaging the electrodes. This method significantly reduces costs and encourages more responsible use of resources in 2D materials device fabrication.
