Resumen
El microscopio de tunelamiento cuántico (MTC) es un magnifico instrumento de laboratorio capaz de producir imágenes de resolución atómica, y molecular. El MTC también ha probado su capacidad de crear patronos geométricos y estructuras de escala nanométrica sobre la superficie de los sólidos. De esta forma el MTC permite concebir una futura tecnología de sistemas y dispositivos de nanoescala hasta alcanzar el límite de la integración con manipulación de átomos individuales. EII este artículo se ilustran las novedosas posibilidades del MTC y se presentan resultados y cifras que corroboran el potencial de este microscopio en la industria electrónica del siglo XXI. En particular. se presentan resultados experimentales sobre formación nanoestructuras, del orden de los 100 A sobre superficies de oro y bicapas de oro-grafito, con un microscopio de la Burleigh Instrumentos operando en aire
The scanning tunneling microscope (STM) is a superb laboratory instrument for atomic and molecular imaging of surfaces. The STM has also proved to be a powerful tool in the manufacture of nanometer size patterns and structures on solid surfaces. Likewise, the STM permits to conceive a future technology of nanoscale systems and devices capable of reaching the limit of integration involving sigle atom manipulations. This paper illustrates the novel possibilities of STM and shows results and figure that corroborate the potencial use of this microscope in the XXI century electronics industry. In particular, we report experimental results of nanostructures formation, of 100 A order on gold surfaces and gold-graphite bilayers, with a Burleigh Instruments microscope operating in air.
