Abstract
In designing nanoscale optoelectronic devices based on a small number of active quantum dots it is of interest to consider that semiconductor nanocrystals quantum dots are observed to blink “on” and “off” The time probability distributions scale as an inverse power law for colloidal quantum dots and exponentially for selfassembled dots Possible mechanisms that cause the inverse power law and exponential blinking statistics are discussed in the paper and the relevance to quantumdot based system architectures is discussed
