Trions are what scientists call “quasiparticles,” bundles of energy, electric charge and spin that zoom around inside semiconductors.   Trions were first observed in quantum wells in 1993 and shortly thereafter in GaAs-AlGaAs quantum wells. Trions were were predicted and found in the photoluminescence and absorption spectra of various optically …

Humans view the intensity of light as the various colors of the spectrum. Characteristics of light include amplitude (intensity), frequency (color), polarization, and coherence. The human eye has cone cells, that correspond reflected light from objects into colors which range from wavelengths of approximately 400-700nm. Polarization, the direction in which …
