Pulse flat band potential

For semiconductor colloidal particles pulsed radiolysis techniques [103] have also been used to derive the flat-band potential.

The inbuilt depletion layer voltage is decreased with the bias shifting in negative direction. The flat-band potential is at - 0.95 V. The reduced redox ions that can discharge the holes at the surface are 0.005 M 1,1 -dimethylferrocene (Reproduced from upper part of Fig. 4, Ref. [16])...
