In solar energy application, often we should know the sun position at each instant. With the sun position calculation, I think we can establish a database for this purpose. Then we can use-it for tracking the sun using for example any circuit with an embedded PIC. Other methods were used. Which is the best ?

No title

The substrate which supports the multilayer thin films is generally considered as infinity. In reality, any substrate is finite. It is also thick versus the thin films.

From DOS (density of state) calculation, can we determine the type (n or p) of the studied semiconductor?

Density of state or band structure energy can be obtained using any theoretical approach, for example DFT. So, from these results, is it possible to determine the type (n or p) of a given...
