Synthesis of flexible electronic devices using low-cost, naturally abundant materials (e.g., MoS2) directly onto inexpensive polymeric materials promises manufacturing of flexible 2D devices at economically viable scales enabling use of their unique physics in grand challenge areas of energy, healthcare, and national security. Recently-proven approaches for low temperature 2D synthesis suitable for flexible substrates developed by the authors include growth of amorphous materials with subsequent photonic annealing to access crystalline domain sizes up to several microns. This approach has been demonstrated for synthesis of large area ultrathin monolithic layers as well as MoS2/WS2/BN multilayers with pristine interfaces, allowing interrogation of intrinsic properties of 2D materials and their heterostructures as they apply to diverse optoelectronic devices. Detailed kinetic studies of crystal formation were accomplished through high throughput in-situ Raman spectroscopy at different surface temperatures and ambient conditions. With this technique, heterostructures were formed incorporating multiple TMD layers that were annealed simultaneously, and insights into the role of surface diffusion for metal and chacogen speices, and factors dictating activation energy for two-dimensional crystallization will be discussed.
