Abstract:
The expression of transmission coefficient have been deduced for a one-dimensional multi-barrier structure,the effect of resonant transmission,with different transverse energy and different incident angles in four barrier structure,have been calculated.As can be seen by calculation that the multi-barrier structure is equivalent to a filter which has filtration function for incident particles.This structure can control the transverse energy and angles of incident particles so that only particles with certain energy pass.Hence,in this way,we can select out different particles with different energy.Meanwhile,this plays an important role in the area of analysis of crystal electron scattering and electron spectroscopy.
