This can be done by creating a dislocation loop in the material.
2.
At the end, both point defects and dislocation loops remain.
3.
They perturbed the silicon itself, put in these dislocation loops and forced the electrons to emit light.
4.
At large areal island densities ( smaller spacing ), curvature effects from neighboring clusters will cause dislocation loops to form leading to defected island creation.
5.
And the dislocation does not bend past the semicircular equilibrium state, it will not form a dislocation loop and instead revert to its original state.
6.
When a voltage was applied at room temperature to the crystal produced by Homewood's group, charges were prevented from moving by these rings, which are called dislocation loops.
7.
Provided that the area directly above the dislocation loop is defect-free ( no non-radiative recombination possible ), the electrons will fall back into the valence shell by radiative recombination, thus emitting light.
8.
The process results in a dislocation loop around A and B in the slip plane which expands under continued shear stress, and also in a new dislocation line between A and B which, under renewed or continued shear, can continue to generate dislocation loops in the manner just described.
