Mechanism of Hot‐Carrier Photoluminescence in Sn‐Based Perovskites
Advanced Materials, Volume 37, Issue 5, February 5, 2025.Schematic illustrating the two dominant processes in tin‐iodide perovskites at the band edge: 1) Filling of carriers at the band edge extrema as they cool. 2) Cooling of carriers emitting a longitudinal optical (LO) phonon. The inset shows the dephasing of a longitudinal optical phonon studied by impulsive vibrational spectroscopy in this work ...

Tunable ring resonator filter for OFDM Transmission systems [PDF]
, 1995 A novel tunable filter is theoretically demonstrated. It is based on a ring resonator with an amplifier and a noise filter in the loop. This optoelectronic device has potential as a high-sensitivity receiver and as a tunable demultiplexer in OFDM ...

Chemistry – A European Journal, Volume 31, Issue 5, January 22, 2025.New 2D black phosphorus (bP)–phthalocyanine nanohybrids were prepared by liquid phase exfoliation of bP crystals with phthalocyanine (Pc) and Mn phthalocyanine (MnPc). Spectroscopic analyses revealed the development of heterostructures due to the interaction of bP with the aromatic and heteroaromatic rings of Pc, as well as coordinative bonds between P

Electric Field Cycling of Physisorbed Antibodies Reduces Biolayer Polarization Dispersion
Advanced Science, Volume 12, Issue 1, January 9, 2025.The effects of electric field cycling (EF‐cycling) on anti‐IgM layers physisorbed on Au, are studied. Physisorption of anti‐IgM lowers the Au work function, while a reduced dispersion of the sample's overall dipole moment, occurs after cycling, indicating that the electric field serves as an annealing process, guiding the physisorbed proteins toward a ...

Theory of high-order harmonic generation for gapless graphene
New Journal of Physics, 2018 We study the high-harmonic spectrum emitted by a single-layer graphene, irradiated by an ultrashort intense infrared laser pulse. We show the emergence of the typical non-perturbative spectral features, harmonic plateau and cut-off, for mid-infrared ...
