1/ƒ noise for intermittent quantum dots exhibits nonstationarity and critical exponents
Author(s):Sadegh, Sanaz; Barkai, Eli; Krapf, Diego
Format:born digital; ariticles
The power spectrum of quantum dot (QD) fluorescence exhibits 1/ƒ β noise, related to the intermittency of these nanosystems. As in other systems exhibiting 1/ƒ noise, this power spectrum is not integrable at low frequencies, ...
