The atomically thin 2D nature of suspended graphene membranes holds promising in numerous technological applications. In particular, the outstanding transparency to electron beam endows graphene membranes great potential as a candidate for specimen support of transmission electron microscopy (TEM). However, major hurdles remain to be addressed to acquire an ultraclean, high‐intactness, and defect‐free...
In article number 1700639, large‐area and high‐quality suspended graphene membranes are fabricated via polymer‐free clean transfer of sub‐centimeter graphene single crystals from copper foil onto transmission electron microscopy (TEM) grids by Zhongfan Liu, Hailin Peng, and co‐workers. Meanwhile, the high‐yield graphene liquid cells are fabricated via efficient π–π stacking of two clean single‐crystal...
