The latest releases are: 3.08įixed error ‘Parameter is not valid’. SVGMarks is free to use (giving back for the free digitizers the author used prior to developing SVGMarks).
Secondly, the exact image dimensions and coordinates of the image center are required to scale and place an image in the correct position in the design file. Firstly, the coordinate system of the image usually does not coincide with the coordinate system of the design file (even if the images are taken with great care a slight rotation is always present). Image processing is necessary for two reasons. The software presented here ( SVGMarks) is used to process images of graphene flakes and marks such that they can be imported into a design file. The coordinate system is used to precisely locate graphene on a chip allowing design of lithographic patterns. For this reason, patterning graphene (or any other sparse and randomly distributed set of objects) requires deposition of graphene on a prepatterned substrate containing a coordinate system (usually defined by a matrix of marks). The probability of obtaining monolayer graphene in this process is very small (a few monolayers per mm 2).
Such deposited graphene flakes are randomly distributed on a chip. Nanoscale Device Group Graphene software - SVGMarksĭevices based on graphene and related 2D materials (‘graphene’ for short) are usually fabricated by patterning graphene deposited on a Si substrate by mechanical exfoliation.
