My sample ZnS is showing negative photocurrent, but CdS, CdZnS photocurrent is positive. why ZnS is showing negative current, i recheck it many times.
I prepared CdZnS photocatalyst for hydrogen production.
As described in the Multifractal detrended fluctuation analysis (MFDFA) algorithm, it at first calculates the profile of the time series, and then other steps are operated on the profile....
