En este artículo se explica el proceso de creación del microscopio electrónico de transmisión y la técnica de microscopía electrónica. A su vez, se describen dos experimentos, el de interferencia de un solo electrón y el efecto Ahrenberg Siday-Aharonov-Bohm, los cuales evidencian aspectos del comportamiento de los electrones, que no podrían ser explicados desde la mecánica clásica y que se hacen evidentes gracias a este tipo de instrumentos y al uso de la holografía electrónica. Finalmente, se muestran algunos de los trabajos actuales en los que se utiliza la microscopía electrónica de transmisión en el grupo de microscopía electrónica del departamento de física.
In this article, the creation process of the Transmission electron microscope (TEM) is shown. Additionally, two experiments of a single electron interference and the ASAB (hrenberg Siday-Aharonov-Bohm)eect is described. This to evidence aspects of the electron behavior that couldn't be explained by the classical mechanics and result evident using TEM and electron holography. To nish some of the work done in the electron microscopy using TEM is presented.
