Journal Article
Cottam, N. D., Zhang, C., Turyanska, L., Eaves, L., Kudrynskyi, Z., Vdovin, E. E., …Makarovsky, O. (2020). Defect-assisted high photoconductive UV-VIS gain in perovskite-decorated graphene transistors. ACS Applied Electronic Materials, 2, 147-154. https://doi.org/10.1021/acsaelm.9b00664

Recent progress in the synthesis of high stability inorganic perovskite nanocrystals (NCs) has led to their increasing use in broadband photodetectors. These NCs are of particular interest for the UV range as they have the potential to extend the wav...

High-Frequency Elastic Coupling at the Interface of van der Waals Nanolayers Imaged by Picosecond Ultrasonics (2019)
Journal Article
Greener, J. D., de Lima Savi, E., Akimov, A. V., Raetz, S., Kudrynskyi, Z., Kovalyuk, Z. D., …Gusev, V. E. (2019). High-Frequency Elastic Coupling at the Interface of van der Waals Nanolayers Imaged by Picosecond Ultrasonics. ACS Nano, 13(10), 11530-11537. https://doi.org/10.1021/acsnano.9b05052

Although the topography of van de Waals (vdW) layers and heterostructures can be imaged by scanning probe microscopy, high-frequency interface elastic properties are more difficult to assess. These can influence the stability, reliability and perform... Read More about High-Frequency Elastic Coupling at the Interface of van der Waals Nanolayers Imaged by Picosecond Ultrasonics.

Two-Dimensional Covalent Crystals by Chemical Conversion of Thin van der Waals Materials (2019)
Journal Article
Sreepal, V., Yagmurcukardes, M., Vasu, K. S., Kelly, D. J., Taylor, S. F. R., Kravets, V. G., …Nair, R. R. (2019). Two-Dimensional Covalent Crystals by Chemical Conversion of Thin van der Waals Materials. Nano Letters, 19(9), 6475-6481. https://doi.org/10.1021/acs.nanolett.9b02700

Most of the studied two-dimensional (2D) materials have been obtained by exfoliation of van der Waals crystals. Recently, there has been growing interest in fabricating synthetic 2D crystals which have no layered bulk analogues. These efforts have be...
