noble gas, for example, argon. Under the electrical eld
between the anode (attributed to the substrate) and the
cathode (attributed to the source), the glow discharge
appears. The ionized gas ejects the atoms of the mate-
rial from the source and moves them into the substrate.
By changing sources, it is possible to deposit various
materials and in this way form a multilayer structure.
In the thin lm technology, molecular beam epitaxy
(MBE) technique is very important (Figure 3.79). In this
technique, it is possible to obtain almost perfect crystal
structure because deposited lm mimics the st ...
