Benvenuti nell'Anagrafe della Ricerca d'Ateneo
La valutazione delle attività di ricerca che si svolgono nelle università ha assunto un'importanza rilevante sia per l'intero sistema universitario sia all'interno di ogni singolo ateneo. Roma Tre si è quindi dotata di idonei strumenti informativi in grado di supportare al meglio le azioni di monitoraggio e di valutazione delle attività di ricerca svolte nei propri dipartimentied ha realizzato una Anagrafe della Ricerca di Ateneo.
EnglishWe report on a scanning tunnelling microscope equipped with a piezoelectric inertial slider micropositioner. For any orientation, the proposed device allows an approach down to the tunnelling distance from the tip. The approach process is fully automated by a personal computer that generates the driving signals. Continuous motion at a speed of 5 mm s-1 and single-step advancement down to 50 Å are obtained. The microscope, due to its mechanical symmetry and rigidity, can operate with atomic resolution, using a few stage vibration isolation stacks. The instrument can easily be modified to operate as an atomic force microscope with a fibre-optic-interferometer displacement sensor.
