Method OF Transfer Printing

Detailed Technology Description

2-dimensional (2D) materials are characterized as being one or two atoms thick. Graphene (image) is by far the best known 2D material. However, there are many other 2D materials with attractive properties (e.g. hexagonal boron nitrides (hBN), transition metal dichalcogenides, etc.). Due to their superior physical properties, graphene and related 2D materials have the potential to revolutionize many industries, enable development of new devices, and provide new functionalities to existing technologies. In short, these materials have the potential to be disruptive and pervasive. Despite their overwhelming promise, however, industrial scale manufacture of these materials is not yet a reality, due in part to an inability to control layer number and to print over large surface areas.  To address this problem, scientists at UMass Amherst have engineered a high-precision printing method that is compatible with current industrial manufacturing processes. This simple method allows single layer 2D material to be patterned, transferred and printed onto a substrate, enabling the fabrication of novel 2D heterostructures devices. Thus, this method will facilitate the assembly of novel devices and enable large-scale manufacture of devices with designed properties. TECHNOLOGY DESCRIPTION  ADVANTAGES •       Single layer printing of 2D materials•       Control over number of layers•       High precision printing over large areas•       Compatible with current processing technology  APPLICATIONS•       High Performance Electronic Devices•       Optical Detectors•       Energy Storage•       Hypersensitive Sensors  ABOUT THE INVENTORDr. Qiangfei Xia is a Professor in the Department of Electrical and Computer Engineering and a recipient of a DARPA Young Faculty Award and an NSF Career Award.   AVAILABILITY: Available for Licensing and/or Sponsored Research  DOCKET: UMA 15-049  PATENT STATUS: Patent Pending  NON-CONFIDENTIAL INVENTION DISCLOSURE  LEAD INVENTOR: Qiangfei Xia, Ph.D.  CONTACT:  2-dimensional (2D) materials are characterized as being one or two atoms thick.
