What is the significance of the negative and positive shifts in the flat band potential?

Dear all, I would like to know about the significance of the negative (cathodic) and positive (anodic) shifts in the flat band potential, in the case of the photoelectrodes. How do these shifts...

Why does sometimes the photo-current in an photo-electrode keep increasing instead of decreasing on illumination?

When an electrode made of semiconductor nanotubes/nanowires etc is illuminated an overshoot or transient maximum in the photocurrent is observed. The photocurrent gradually exponentially decreases...

Physics: Why do we describe light by referring to its wavelength, but microwaves and radar pulses by referring to their frequency?

In physics, the description of the properties of light generally refers to its wavelength (nm), while in the range of microwaves and radio waves we refer to the frequency of a signal (e.g. kHz or...

Why are the velocities so high in my Boussinesq approximation Fluent simulation?

Hello, I have a mechanism where air rises due to convective flows. In this simulation, nothing is driving the air except this. I understand that the Boussinesq approximation only works for small...
