Detecting ultra-low ozone and hydrogen concentrations with CsPbBr microcrystals direct grown on electrodes
Aikaterini Argyrou, Konstantinos Brintakis, Athanasia Kostopoulou +5
Highly stable ozone and hydrogen sensing elements were fabricated based on well-crystalline rounded cube-shaped CsPbBr submicron crystals, synthesized by a facile solution proc…
Polarization dependent spike formation on black silicon via ultrafast laser structuring
Evangelos Skoulas, Alexandros Mimidis, Ioanna Demeridou +2
A comparative experimental and theoretical investigation is presented that centres on the effects of structuring black silicon surfaces with linearly, circularly and azimuthally po…
Probing valley population imbalance in transition metal dichalcogenides via temperature-dependent second harmonic generation imaging
Leonidas Mouchliadis, Sotiris Psilodimitrakopoulos, George Miltos Maragkakis +5
Degenerate minima in momentum space - valleys - provide an additional degree of freedom that can be used for information transport and storage. Notably, such minima naturally exist…
Robust B-exciton emission at room temperature in few-layers of MoS2:Ag nanoheterojunctions embedded into a glass matrix
Abdus Salam Sarkar, Ioannis Konidakis, Ioanna Demeridou +3
Tailoring the photoluminescence (PL) properties in two-dimensional (2D) molybdenum disulfide (MoS2) crystals using external factors is critical for its use in valleytronic, nanopho…
