产品概述
高取向热解石墨（HOPG）ZYB品质，马赛克铺展度：1.0 ± 0.4度，双面，片材尺寸——10x10毫米
双面HOPG可双面使用，其性能在深度方向上保持不变。
单面片材的非工作面呈哑光质地，无反光且不可劈裂。单面片材的工作面可劈裂次数较双面基底有限。单面片材的物理特性随深度变化。
HOPG晶体广泛应用于扫描隧道显微镜（STM）基底。使其适用于该领域的最显著特征是极致平滑的表面与优异的导电性。
HOPG的层状结构极大简化了样品制备流程：将双面胶带粘附于HOPG片后剥离，即可获得平整光滑的新鲜导电表面。该表面既可直接用于STM检测，亦可作为其他研究材料的基底。
HOPG本身亦是STM研究的理想对象。可测量其表面粗糙度、微观表面特征、碳原子排列等参数。此外，原子级分辨率的HOPG图像可用于校准STM系统，实现高分辨率成像。
Highly Oriented Pyrolytic Graphite (HOPG) ZYB Quality, Mosaic Spread: 1.0 ± 0.4 degrees, double-sided, piece size – 10x10mm, thickness 2mm.
Double-sided HOPG can be used from both sides and its properties are not changed in depth.
For single-sided piece the not working side is mat, glare less and can’t be cleaved. The number of working side cleavages of one-sided piece is limited in comparison with double sided substrate. The properties for one-sided piece are changed in depth.
HOPG crystals are widely used as substrates in STM (Scanning Tunneling Microscopy). The most distinguishing features of HOPG which enable this application are a very smooth surface and electro conductivity.
HOPG has a layered structure which makes sample preparation very simple. By pressing a double-stick tape to a HOPG piece and peeling it off, one gets a fresh conductive surface which is very smooth. This surface can be examined in STM or serve as a substrate for other materials under investigation.
HOPG itself is an interesting object for STM investigations. One can measure the surface roughness, microscopic surface features, arrangement of the carbon atoms on the HOPG surface, etc. Besides, HOPG images at the atomic level can be used for calibrating STM for high-resolution imaging.

备注：
HOPG because of its layered structure cleaves almost like mica. The usual approach is to take a piece of tape, press it onto the flat surface, pull it off and the tape invariably takes with is a thin layer of HOPG. You also can try to make cleaving in perpendicular direction to have more smooth surface. This freshly cleaved surface is what is used as sample substrate material.
