Abstract :
Blinking statistics of quantum dot has gained more attention from past few years. In this regard, many experiments were conducted and various theories have been proposed to explain this phenomenon. However, this is still a gray area and need to investigate blinking statistics of quantum dot (QD). In the present work, the blinking statistics of quantum dot has been simulated by Monte Carlo algorithms based on the random walk model. Our finding shows that experimental result could be explained by three-dimensional Levy random walk model if we apply suitable bias, the bias being the Columbic interaction between electrons and ionized atoms. The power law parameter is fitted for different light intensity and tried to match with the experimental results.
