Geometric band properties in strained monolayer transition metal dichalcogenides using simple band structures
Aas, Shahnaz; Bulutay, Ceyhun (American Institute of Physics, 2019)Monolayer transition metal dichalcogenides (TMDs) bare large Berry curvature hotspots readily exploitable for geometric band effects. Tailoring and enhancement of these features via strain is an active research direction. ... -
Graphene-Based Adaptive Thermal Camouflage
Salihoğlu, Ömer; Uzlu, H. B.; Yakar, Ozan; Aas, Shahnaz; Balci, Osman; Kakenov, Nurbek; Balci, S.; Olcum, S.; Süzer, Şefik; Kocabas, Coşkun (American Chemical Society, 2018)In nature, adaptive coloration has been effectively utilized for concealment and signaling. Various biological mechanisms have evolved to tune the reflectivity for visible and ultraviolet light. These examples inspire many ... -
Strain dependence of photoluminescence and circular dichroism in transition metal dichalcogenides: a k. p analysis
Aas, Shahnaz; Bulutay, Ceyhun (OSA - The Optical Society, 2018)Within a two-band k p method we analyze different types of strain for the k valley optical characteristics of a freestanding monolayer mos2 Mose2 Ws2 andwse2. we predict that circular polarization selectivity for energies ... -
A theoretical study of strained monolayer transition metal dichalcogenides based on simple band structures
Aas, Shahnaz (Bilkent University, 2019-10)This doctoral thesis deals with optoelectronic and geometric band properties of two-dimensional transition metal dichalcogenides (TMDs) under applied strain. First, we analyze various types of strain for the K valley ...
