Kyma Technologies, Inc., a leading supplier of advanced materials solutions that promote safety and energy efficiency, is pleased to announce the launch of crystalline 2D MoS₂ materials and growth tools as an important new product line.

Crystalline two-dimensional (2D) molybdenum disulfide (MoS2) materials fall in the family of crystalline 2D transition metal dichalcogenides (TMDs), which are atomically thin semiconductors which are being explored worldwide for their potential to support a number of future applications including flexible electronics and flexible optoelectronics.

Kyma recently won support by the US Air Force to develop the capability of fabricating large diameter high quality crystalline 2D MoS₂ materials and more recently won support by the US Army to incorporate those materials in radio frequency (RF) electronics. Both of those projects are progressing nicely and have enabled Kyma to begin offering crystalline 2D MoS2 materials to the market.

Kyma uses a novel 2D crystal growth tool to grow crystalline 2D MoS2 materials. The crystal growth tool was designed by Kyma and features the ability to explore different source chemistries in support of the growth of a variety of different 2D crystalline materials (e.g., MoS₂, WS₂, MoSe₂, WTe₂). To date Kyma has deposited over 100 MoS2 films, experimenting with growth conditions and surface preparation approaches. Their effort is supported by an in-house modelling effort and a close collaboration with Professor Joshua Robinson's group at Pennsylvania State University.

Kyma's MoS₂ materials include regions with single monolayer crystallites and multiple monolayer crystallites, based on well-established Raman spectroscopy and photoluminescence characterization methods.

Kyma's initial efforts utilize 2" diameter substrates and have focused on nucleation and growth of large area single monolayer MoS2 crystalline grains. So far the highest quality triangular crystallites are located in a narrow region of the wafer; enhanced deposition uniformity as well as novel source chemistries will be emphasized in the coming months.

"We have come a long way, from initial collaboration discussions with Josh Robinson of Penn State, to partnering with Josh and transitioning one of his WS₂ growth processes to Kyma (as announced previously) and extending it to larger diameter, to winning Air Force and Army support and producing our own materials. Our overall approach to the tool and process for growing MoS₂ has been to reproduce best practices established in academia and to translate that to a commercially robust yet flexible prototype crystal growth tool," commented Company president & CEO Keith Evans.

"These materials will continue to evolve yet their characteristics are already exciting enough to begin supplying them to next generation device scientists and engineers. We are offering steep discounts to those customers who will help us understand our materials better and provide feedback on how we might further engineer their properties."
