Title in Portuguese
Manipulação transversal de feixes atômicos para possível uso em litografia atômica
Keywords in Portuguese
Feixes atômicos
Nanolitografia atômica
Abstract in Portuguese
Desde o desenvolvimento de técnicas para controlar o movimento atômico usando a força de pressão de radiação, muitas aplicações tem sido sugeridas e implementadas. Entre estas, o aprisionamento atômico e o desenvolvimento de estruturas espaciais com átomos frios merece atenção especial devido à sua potencial aplicação em depósitos superficiais como litografia. Realizamos, neste trabalho, um estudo sobre feixes atômicos e sua desaceleração e compressão espacial. Realizamos também estudos numéricos sobre a formação de estruturas em anéis em feixes atômicos, verificando ser factível, e estudando também a compressão destas estruturas espaciais, com vistas a possíveis aplicações em nanolitografia atômica.

Atomic beams
Atomic nanolitography
Abstract in English
From the very beginning of the development of atomic motion control techniques using the radiation pressure force, a variety of applications have been suggested and implemented. Of all these, atomic trapping techniques and the development of spatial structures using cold atoms deserves special attention due to its potential application to surface deposition such as lithography. In the present work, we perform a study on atomic beams and their deceleration and spatial compression. We also perform numerical studies and present experimental observation of the realization of spatial ring structures in atomic beams, verifying its factibility, and we study the compression of such ring-shaped structures with application in atomic nanolithography as the ultimate goal.
