Abstract
GaAs has been injected into chrysotile asbestos channels. GaAs quantum wires (nanocylinders) with diameters (similar to) 6 nm have been obse rved in the channels by means of transmittance electron microscopy. Po larized optical absorption spectra of asb-GaAs (chrysotile asbestos co ntaining GaAs wires) have been studied. A high anisotropy of the absor ption has been observed, and intersubband transitions in the visible l ight region due to a strong quantum size effect have been found.
