Detecting ultra-low ozone and hydrogen concentrations with CsPbBr$_3$ microcrystals direct grown on electrodes

Autor: Argyrou, Aikaterini, Brintakis, Konstantinos, Kostopoulou, Athanasia, Gagaoudakis, Emmanouil, Demeridou, Ioanna, Binas, Vassilios, Kiriakidis, George, Stratakis, Emmanuel

Highly stable ozone and hydrogen sensing elements were fabricated based on well-crystalline rounded cube-shaped CsPbBr$_3$ submicron crystals, synthesized by a facile solution process performed under ambient conditions. It is shown that such elements

Polarization dependent spike formation on black silicon via ultrafast laser structuring

Autor: Skoulas, Evangelos, Mimidis, Alexandros, Demeridou, Ioanna, Tsibidis, George D., Stratakis, Emmanuel

A comparative experimental and theoretical investigation is presented that centres on the effects of structuring black silicon surfaces with linearly, circularly and azimuthally polarized laser pulses under SF6 ambient atmosphere. It is shown that th

Probing valley population imbalance in transition metal dichalcogenides via temperature-dependent second harmonic generation imaging

Autor: Mouchliadis, Leonidas, Psilodimitrakopoulos, Sotiris, Maragkakis, George Miltos, Demeridou, Ioanna, Kourmoulakis, George, Lemonis, Andreas, Kioseoglou, George, Stratakis, Emmanuel

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 in the band structure of transition metal dichalcogenides (TMDs). Whe

Publikováno v: Sci Rep 10, 15697 (2020)

Tailoring the photoluminescence (PL) properties in two-dimensional (2D) molybdenum disulfide (MoS2) crystals using external factors is critical for its use in valleytronic, nanophotonic and optoelectronic applications. Although significant effort has
