All-dry flip-over stacking of van der Waals junctions of 2D materials using polyvinyl chloride
Abstract We demonstrated an all-dry polymer-to-polymer transfer technique for two-dimensional (2D) crystal flakes using a polyvinyl chloride (PVC) layer deposited on a piece Zinc of polydimethylsiloxane (PDMS).Unexpectedly, the pickup/release temperatures were modified in wider temperature range simply by changing the thickness of the PVC layer tha
