Role of the Solid–Aqueous Medium Interface in Transferring Light-Induced Excitation of Silicon

Resumo

An effect has been discovered that irradiation of a silicon sample by light changes the properties of another silicon sample several centimeters away from the former. This effect is observed if the samples are in contact with a fluoroplastic–NaCl aqueous solution system or a sodium-containing glass–water system. Results have been treated based on the earlier model of hypersonic wave generation by light in a silicon–native oxide system and the hypothesis for hypersonic wave propagation along a solid–aqueous medium interface due to the presence of Na⁺–[H₂O]_n clusters.
