La influencia de la mecánica cuántica en la física y tecnología de los semiconductores: fundamentos, aplicaciones y perspectivas

Quantum mechanics constitutes the cornerstone of modern semiconductor physics. From the description of the electron as an entity of wave-particle nature to the understanding of energy band structure, tunneling effects, and quantum confinement, the operating principles of contemporary electronic devices transistors, diodes, lasers, detectors, and integrated circuits derive directly from quantum laws. This paper rigorously analyzes the relationship between quantum theory and semiconductor physics, addressing theoretical foundations, mathematical models, technological applications, and future perspectives in microelectronics and nanotechnology. Fundamental equations, experimental results, and technological projections are integrated within a scientific framework, highlighting the pivotal role of quantum mechanics in the evolution and physical limits of current and emerging semiconductor devices.
