MXenes and Transition Metal Dichalcogenides

Chinese Academy of Sciences leads the listed research activity with 848 documents in the 24-month window, followed by the University of Chinese Academy of Sciences with 483 and Japan National Institute of Materials Science with 342. Their reported work includes quantum-grade TMD growth, exciton studies and van der Waals heterostructures. These figures describe recorded activity, not a ranking of research quality.

The data list $208,841,607 in grants across 450 awards since 2020. They also record 17 funding rounds totaling $216,318,607,964. That round total includes organization-level investments that are not clearly specific to MXenes or TMDs, so it should not be treated as a direct measure of funding for this field. The grant total is also an aggregate rather than a breakdown by material or project.

Samsung is listed with 29 patent records, Samsung Electronics Co., Ltd. with 28, and Taiwan Semiconductor Manufacturing Company with 25. Drexel University follows with 20. The patent-holder list includes both corporate and academic organizations, and the figures represent listed patent activity rather than a measure of commercial deployment or patent quality.

No: patent activity declined 43.1% in the last 12 months compared with the previous 12 months. The data list 731 patents in the 24-month window. This decline appears alongside a smaller 3.5% fall in publications over the same comparison period, so recent activity is not expanding uniformly across document types.

Recent work includes strongly bound charge-transfer interface excitons in lateral MoSe2–WSe2 heterostructures, reported in September 2026 by researchers including Indian Institute of Technology Jammu and Friedrich - Schiller University of Jena. A September 2026 study from University of Tübingen and collaborators examined high-speed photoresponse in CVD-grown lateral TMD heterostructures. Both efforts address how interface design affects device behavior.

Recent methods include substrate-assisted flux growth for quantum-grade TMDs, colloidal chemistry for phase-selective monolayer synthesis, and atomic layer etching of MoS2 using cyclic argon and CF4 plasmas. Emerging terms in the data include excitons, monolayers, energy gap and heterojunctions. These point to work spanning material synthesis, phase control and the study of electronic and optical behavior.

The listed approaches are MXene compositions, semiconducting layers, metallic and superconducting layers, Janus and alloyed layers, van der Waals heterostructures, and scalable growth. They differ in whether they tune composition, electronic phase, layer asymmetry, interfaces or manufacturing. The central trade-off is between achieving precisely controlled material properties and producing uniform films that can integrate into devices.

China leads the listed activity with 52,746 documents, or 49.8% of the total, followed by the United States with 20,028 and India with 11,747. South Korea and Japan are also prominent, with 8,420 and 5,188 documents, respectively. These figures reflect document activity and do not directly measure industrial production or investment.

The listed application areas include energy storage, with 6,318 documents; catalysis, with 4,877; sensing and wearables, with 3,573; and optoelectronics and photonics, with 3,039. Electronics and logic, and lubrication and tribology, are also represented. Recent work on excitons and heterostructures supports interest in optical and electronic devices, while energy storage remains a substantial application area.
