“…Using interference from laser beams the deposition of atoms may be manipulated to form sub-wavelength quasi-periodic structures. Five laser beams in a plane with angles of 72 create a Cr structure with fivefold symmetry (Jurdik et al, 2004).…”

For several decades the lattice periodicity of crystals, as shown by Laue, was considered to be their essential property. In the early sixties of the last century compounds were found which for many reasons should be called crystals, but were not lattice periodic. This opened the field of aperiodic crystals. An overview of this development is given. Many materials of this kind were found, sometimes with very interesting properties. In the beginning the development was slow, but the number of structures of this type increased enormously. In the meantime hundreds of scientists have contributed to this field using a multi-disciplinary approach.

“…The method is based on the interaction of a thermal atomic beam with a slightly detuned resonant laser standing wave (SW) resulting in a direct optical manipulation of atoms as described in [5]. By using a combination of laser beams, various structures can be created, such as nanowires and nanodots with 2, 3, 4 or even 5-fold symmetry [6]. Iron nonowires grown in this way however showed no periodic magnetic behavior [5], presumably because of a large background layer.…”

Arrays of magnetic cobalt/chromium (Co-Cr) nanolines are grown by depositing an atomic beam of Co-Cr alloy through a laser standing wave (SW) at λ/2 = 212.8 nm onto a substrate. During deposition, only the chromium atoms are resonantly affected by the optical potential created by the SW, causing a periodic modulation of the chromium concentration and consequently of the magnetic properties. Magnetic force microscopy and magneto-optical Kerr effect studies reveal a patterned magnetic structure on the substrate surface.

“…While there has been a great deal of work in atomic lithography (recent reviews can be found in Refs. 8,9,10), only spatially periodic or quasiperiodic [3,11] patterns have been demonstrated. As this limits the range of applications and usefulness of the technique there is considerable interest in devising approaches that will allow spatially complex structures to be created.…”

We analyze a method for serial writing of arbitrary two-dimensional patterns using optical focusing of a collimated atomic beam. A spatial light modulator is used in a side illumination geometry to create a localized optical spot with secondary maxima that are well separated from the central peak. Numerical simulation of a lithography experiment using a magneto-optical trap as a source of cold Cs atoms, collimation and cooling in a magnetic guide, and optical focusing predicts full width at half maximum pixel sizes of 110 x 110 nm and writing times of about 20 ms per pixel.PACS numbers:

Quasiperiodic structures via atom-optical nanofabrication

Abstract: We deposit a laser-collimated chromium beam onto a substrate through a quasiperiodic laser standing-wave ͑SW͒ tuned above the atomic resonance at the 52 Cr transition 7 S 3 → 7 P 4 o at 425.55 nm. This SW is created by RAPID COMMUNICATIONSPHYSICAL REVIEW B 69, 201102͑R͒ ͑2004͒
