It is characterised by by the mosaic spread angle.\u00a0 HOPG is a laminar material and consists of layered polycrystals resembling a mosaic of monocrystals grains which are slightly disorientated with respect to each other. The size of the individual crystals varies from 1-10um. A lower mosaic spread angle represents a better alignment of the graphite crystals. The best HOPG samples have a mosaic spread value of less than 1 degree. The freshly cleaved HOPG substrates provides atomically flat areas which are used as a specimen substrate and for magnification calibration in scanning probe microscopy techniques (AFM, SPM, STM). Similar to mica,\u00a0 fresh surfaces can be made by cleaving the samples.<br>HOPG is made by annealing graphite under pressure at temperatures over 3000\u00b0C. This conductive material is stable up to 2000\u00b0C.\u00b0<br>Available in three qualities with 0.4, 0.8 and 3.5 degrees mosaic spread. Sample size is 10x10mm and thickness is 1 or 2 mm. The samples are all double sided which means that the full thickness can be used and they can be cleaved from both sides.<\/p>\n\n\n\n<table class=\"wp-block-table\"><tbody><tr><th><img decoding=\"async\" width=\"127\" height=\"119\" class=\"wp-image-10111\" style=\"width: 127px;\" src=\"https:\/\/m-s.it\/wp-content\/uploads\/2020\/02\/10-008311-10-008322-10-008333-10-008341-10-008342.jpg\" alt=\"\"><\/th><th><strong>ZYA grade HOPG, 0.4\u00b0mosaic spread, double sided, 10 x10 x 1mm chip<\/strong><\/th><\/tr><tr><td><strong>Product # <\/strong><\/td><td><strong>Unit<\/strong> <\/td><\/tr><tr><td><strong>10-008311<\/strong> <\/td><td>each<\/td><\/tr><\/tbody><\/table>\n\n\n\n<table class=\"wp-block-table\"><tbody><tr><th><img decoding=\"async\" width=\"127\" height=\"119\" class=\"wp-image-10111\" style=\"width: 127px;\" src=\"https:\/\/m-s.it\/wp-content\/uploads\/2020\/02\/10-008311-10-008322-10-008333-10-008341-10-008342.jpg\" alt=\"\"><\/th><th><strong>ZYA grade HOPG, 0.4\u00b0mosaic spread, double sided, 10 x10 x 2mm chip<\/strong><\/th><\/tr><tr><td><strong>Product # <\/strong><\/td><td><strong>Unit<\/strong> <\/td><\/tr><tr><td><strong>10-008322<\/strong>  <\/td><td>each<\/td><\/tr><\/tbody><\/table>\n\n\n\n<table class=\"wp-block-table\"><tbody><tr><th><img decoding=\"async\" width=\"127\" height=\"119\" class=\"wp-image-10111\" style=\"width: 127px;\" src=\"https:\/\/m-s.it\/wp-content\/uploads\/2020\/02\/10-008311-10-008322-10-008333-10-008341-10-008342.jpg\" alt=\"\"><\/th><th><strong>ZYB grade HOPG, 0.8\u00b0mosaic spread, double sided, 10 x10 x 1mm chip<\/strong><\/th><\/tr><tr><td><strong>Product # <\/strong><\/td><td><strong>Unit<\/strong> <\/td><\/tr><tr><td><strong>10-008333<\/strong> <\/td><td>each<\/td><\/tr><\/tbody><\/table>\n\n\n\n<table class=\"wp-block-table\"><tbody><tr><th><img decoding=\"async\" width=\"127\" height=\"119\" class=\"wp-image-10111\" style=\"width: 127px;\" src=\"https:\/\/m-s.it\/wp-content\/uploads\/2020\/02\/10-008311-10-008322-10-008333-10-008341-10-008342.jpg\" alt=\"\"><\/th><th><strong>ZYH grade HOPG, 3.5\u00b0mosaic spread, double sided, 10 x10 x 1mm chip<\/strong><\/th><\/tr><tr><td><strong>Product # <\/strong><\/td><td><strong>Unit<\/strong> <\/td><\/tr><tr><td><strong>10-008341<\/strong> <\/td><td>each<\/td><\/tr><tr><td><strong>10-008341-5<\/strong> <\/td><td>pkg\/5<\/td><\/tr><\/tbody><\/table>\n\n\n\n<table class=\"wp-block-table\"><tbody><tr><th><img decoding=\"async\" width=\"127\" height=\"119\" class=\"wp-image-10111\" style=\"width: 127px;\" src=\"https:\/\/m-s.it\/wp-content\/uploads\/2020\/02\/10-008311-10-008322-10-008333-10-008341-10-008342.jpg\" alt=\"\"><\/th><th><strong>ZYH grade HOPG, 3.5\u00b0mosaic spread, double sided, 10 x10 x 2mm chip<\/strong><\/th><\/tr><tr><td><strong>Product # <\/strong><\/td><td><strong>Unit<\/strong> <\/td><\/tr><tr><td><strong>10-008342<\/strong> <\/td><td>each<\/td><\/tr><tr><td><strong>10-008342-5<\/strong> <\/td><td>pkg\/5<\/td><\/tr><\/tbody><\/table>\n","protected":false},"featured_media":10111,"parent":0,"template":"","categoria_prodotto":[212],"class_list":["post-10855","prodotti","type-prodotti","status-publish","has-post-thumbnail","hentry","categoria_prodotto-consumables"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.3 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>HOPG Substrates \u2013 Highly Ordered Pyrolytic Graphite - Media System Lab<\/title>\n<meta name=\"description\" content=\"Highly Ordered Pyrolytic Graphite is a very pure and highly ordered form of synthetic graphite.
