The direct-to-indirect band gap crossover in two-dimensional van der Waals Indium Selenide crystals (2016)
Journal Article
Mudd, G., Molas, M., Chen, X., Zólyomi, V., Nogajewski, K., Kudrynskyi, Z. R., …Patanè, A. (2016). The direct-to-indirect band gap crossover in two-dimensional van der Waals Indium Selenide crystals. Scientific Reports, 6(1), Article 39619. https://doi.org/10.1038/srep39619

The electronic band structure of van der Waals (vdW) layered crystals has properties that depend on the composition, thickness and stacking of the component layers. Here we use density functional theory and high field magneto-optics to investigate th...

Excitonic mobility edge and ultra-short photoluminescence decay time in n-type GaAsN (2016)
Journal Article
Eßer, F., Winner, S., Patanè, A., Helm, M., & Schneider, H. (in press). Excitonic mobility edge and ultra-short photoluminescence decay time in n-type GaAsN. Applied Physics Letters, 109(18), Article 182113. https://doi.org/10.1063/1.4966949

We use time-resolved photoluminescence (PL) spectroscopy to study the recombination dynamics in Si-doped GaAsN semiconductor alloys with a nitrogen content up to 0.2%. The PL decay is predominantly monoexponential and exhibits a strong energy dispers... Read More about Excitonic mobility edge and ultra-short photoluminescence decay time in n-type GaAsN.

Nanomechanical probing of the layer/substrate interface of an exfoliated InSe sheet on sapphire (2016)
Journal Article
Beardsley, R., Akimov, A. V., Greener, J. D., Mudd, G. W., Sandeep, S., Kudrynskyi, Z. R., …Kent, A. J. (2016). Nanomechanical probing of the layer/substrate interface of an exfoliated InSe sheet on sapphire. Scientific Reports, 6, https://doi.org/10.1038/srep26970

Van der Waals (vdW) layered crystals and heterostructures have attracted substantial interest for potential applications in a wide range of emerging technologies. An important, but often overlooked, consideration in the development of implementable d...
