Embodiment 1
[0047] (1) with 4×4cm 2 PDMS membrane as the substrate.
[0048] (2) Use tweezers to pick up highly oriented pyrolytic graphite (HOPG) crystals purchased from Nanjing Xianfeng Nano Co., Ltd., adhere to the surface of the PDMS film, and use multiple PDMS films of the same size to repeatedly cleavage, that is Thin-layer graphene was obtained on PDMS membrane.
[0049] (3) Put the PDMS film sample with graphene into liquid nitrogen to quench quickly, stay for 5 seconds, take it out quickly and place it in room temperature environment, and then the graphene wrinkle structure can be obtained on the surface of the PDMS film.
[0050] (4) Repeat step (3) many times to obtain more wrinkled structures. The obtained folds can be directly observed by an optical microscope, and the folds form a converging network structure, and the pitch of the folds is usually in the range of 1 to 20 microns. The height and width of the wrinkles can be characterized by atomic force microscopy. The di...
Embodiment 2
[0053] (1) in 1×1cm 2 silica gel membrane as the substrate.
[0054] (2) Pick up MoS purchased from Nanjing Xianfeng Nano Co., Ltd. with tweezers 2 Crystals, adhered to the surface of the silica gel membrane, and repeatedly cleaved with multiple silica gel membranes of the same size, that is, a thin layer of MoS was obtained on the silica gel membrane. 2 .
[0055] (3) will have MoS 2 The silica gel film sample is quickly put into liquid nitrogen to quench, stay for 10 seconds, quickly take it out and place it at room temperature, and MoS can be obtained on the surface of the silica gel film. 2 wrinkled structure.
[0056] (4) Repeat step (3) many times to obtain more wrinkled structures. The obtained folds can be directly observed by an optical microscope, and the folds form a converging network structure, and the pitch of the folds is usually in the range of 1 to 20 microns. figure 2 (b) is the multilayer MoS on the silica gel substrate that embodiment 2 makes 2 wrin...
Embodiment 3
[0058] (1) in 1×1cm 2 silica gel membrane as the substrate.
[0059] (2) Use tweezers to pick up WSe purchased from hq-graphene company 2 Crystals, adhered to the surface of the silica gel membrane, and repeatedly cleaved with multiple silica gel membranes of the same size, that is, a thin layer of WSe was obtained on the silica gel membrane. 2 .
[0060] (3) will have WSe 2 The silica gel membrane sample is quickly put into liquid nitrogen to quench, stay for 10 seconds, quickly take it out and place it at room temperature, and then WSe can be obtained on the surface of the silica gel membrane. 2 wrinkled structure.
[0061] (4) Repeat step (3) many times to obtain more wrinkled structures. The obtained folds can be directly observed by an optical microscope, and the folds form a converging network structure, and the pitch of the folds is usually in the range of 1 to 20 microns. figure 2 (c) is the multilayer WSe on the silica gel substrate that embodiment 3 makes 2 w...
