La interacción de la radiación con la materia es un hecho cotidiano en la naturaleza, se pueden recordar fenómenos como la fotosíntesis, interacción de la luz solar con las plantas para generar alimento y la generación de la vitamina D en nuestra piel. Con la formación de sistemas masivos, galaxias, estrellas, planetas, en los albores del universo, se establece la radiación electromagnética, la cual se caracteriza por contener ondas con longitudes desde los kilómetros, ondas de radio, hasta longitudes menores que 10-12 m, rayos gama, pasando por la radiación visible detectada por nuestra retina. En este artículo divulgativo, dirigido al público en general, basado en la investigación de Duque et al [1], se va a tratar acerca de los conceptos involucrados en la interacción de la luz con nanoestructuras semiconductoras.
The interaction of radiation with matter is an everyday event in nature, we can recall phenomena such as photosynthesis, sunlight interaction with plants to produce food and the generation of vitamin D in our skin. With the formation of massive systems, galaxies, stars, planets, in the early universe, electromagnetic radiation was established, which is characterized by containing wavelengths from the kilometer radio waves to shorter lengths 10-12 m, gamma rays, through visible radiation detected by the retina. In this informative article, for the general public, based on the work by Duque et al [1], the objective is to describe the concepts involved in the interaction of light with semiconductor nanostructures.
