What is the underlying reason behind the charge carrier (electron and hole) separation in one dimesional system?

In general, one dimensional nanostructure materials show less possibility of electron and hole recombination because of charge carrier separation. I have read that in some 1D system electrons...

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...
