Low‐ and High‐Frequency Noise in LEDs
physica status solidi (a), Volume 222, Issue 17, September 2025.The results of optical noise measurements for commercially available blue light‐emitting diodes in a range from kHz to MHz are reported. The noise spectra decomposition into components according to the theoretical model is performed. The coincidence of the experimental results with 1/fγ model for the low‐frequency range is proved and a fitting is made.

Brain and Behavior, Volume 15, Issue 7, July 2025.Using fMRI during an object–location memory task, we identified right‐lateralized cortical regions—lateral occipital–temporal cortices, fusiform, and precuneus—as viable brain stimulation targets. Robust behavioral gains and test–retest reliability endorse the paradigm's potential for future brain stimulation research.

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.This paper presents an innovative approach for short‐wave infrared single‐photon detection, achieving a remarkable noise‐equivalent power of 10⁻19 W Hz−1/2 using silicon single‐electron transistors. The detection relies on shift in SET current peaks and occurrence of random telegraph signals under light irradiation, unlocks new possibilities for ...

Advanced Materials Technologies, Volume 10, Issue 5, March 4, 2025.A key role of a bowtie antenna under 940 nm LED excitations is demonstrated to activate two‐level random telegraph signal (RTS) in high‐quality liquid‐gated gate‐all‐around Si nanowire field‐effect transistors. Noise spectroscopy data reflect good tunability of RTS parameters and the opportunity for their optimization. These findings open prospects for
