Quantum Tunneling in Gradual Potentials

Quantum Tunneling in Gradual Potentials

One of the paradigmatic phenomena of quantum mechanics is undoubtedly the so-called tunnel effect, which manifests itself as the possibility of particles on the nanometer scale to traverse potential barriers. This phenomenon, although unintuitive, is so real that it plays a prominent role in current...

One of the paradigmatic phenomena of quantum mechanics is undoubtedly the so-called tunnel effect, which manifests itself as the possibility of particles on the nanometer scale to traverse potential barriers. This phenomenon, although unintuitive, is so real that it plays a prominent role in current technology and constitutes the key mechanism of electronic transport in novel concepts of nanoelectronic devices. In this work, maps of electron density are used to illustrate the spatial and energetic distribution of electrons that propagates through gradual potential barriers, visualizing the wave nature of the electrons and the tunneling phenomenon. In particular, the effect of using gradual barriers rather than rectangular barriers is discussed. Uno de los fenómenos paradigmáticos de la mecánica cuántica es sin duda el llamado efecto túnel, el cual se manifiesta como la posibilidad que tienen las partículas en la escala nanométrica de atravesar barreras de potencial. Este fenómeno, a pesar de ser poco intuitivo, es tan real que juega un papel prominente en la tecnología de nuestros tiempos y constituye el mecanismo dominante del transporte electrónico en nuevos conceptos de dispositivos nanoelectrónicos. En este trabajo se ilustra mediante mapas de la densidad electrónica, la distribución espacial y energética de los electrones que se propagan a través de barreras de potencial graduales, visualizando la naturaleza ondulatoria de los electrones y el fenómeno de tunelaje. En particular, se discute el efecto de utilizar barreras graduales en lugar de barreras rectangulares.
