What are the principles of grazing incidence X-ray diffraction?
The principles of grazing incidence X-ray diffraction (GIXD) are discussed. A sample of a crystalline material is composed of a surface region including its top layer and a bulk part. The effect of the surface region on the intensity of surface X-ray diffraction cannot be generally disregarded.
What is the grazing incidence geometry?
The grazing incidence geometry (Fig. 2) , on the other hand, is surface selective, i.e. largely avoids scattering from the substrate, and it does not require a transparent substrate. This technique is based on the fact that at X-ray energies, the refractive index for most materials is slightly less than1.0. One can therefore have total external

How can a Zener diode be used as a voltage regulator?
Zener Diodes can be used to produce a stabilised voltage output with low ripple under varying load current conditions. By passing a small current through the diode from a voltage source, via a suitable current limiting resistor (RS), the zener diode will conduct sufficient current to maintain a voltage drop of Vout.
