The entropy-driven relaxation of a unique, non-equilibrium step edge configuration on the Ag(1 1 1) surface was observed using time-resolved STM imaging at room temperature. Using the Gibbs–Thomson relation, the relaxation process is quantitatively

Thin films of V2O3 with thickness 4–300 nm were grown on -oriented sapphire substrates by reactive dc magnetron sputtering. X-ray diffraction, pole figure measurements and scanning tunnelling microscopy show high crystallinity and epitaxy to the su

Atom lithography commonly employs self-assem- bled monolayers (SAMs) of alkanethiols which act as resists to protect prepared surfaces. Metastable atomic species such as helium are used to damage the resist, enabling pattern transfer via mask lithogr

The first highly resolved electronic spectra of small non-alkali metal clusters embedded in nanoscopic helium droplets (N≈20000) are presented. The helium droplets serve as an extremely cold liquid matrix with a temperature of 0.37 K. Resonant two-

In this paper we discuss helium droplets as a nanoscale cryostat for a variety of fundamental experiments in condensed matter physics. Specifically, we describe our recent work on the spectroscopy of silver atoms, europium atoms and C60in helium drop

We have recorded the electronic absorption of cold C60 molecules embedded in helium droplets at a temperature of approximately 0.4 K, using a beam depletion technique. We obtain highly resolved spectra in the region between 595 and 650 nm and are abl

In this Letter we study the formation of metal clusters of silver, indium, and europium embedded in helium droplets and present spectroscopic (UV) evidence that, contrary to common belief, metal atoms can be stable inside helium droplets. Our method

The morphology of thin copper films on cleaved GaAs(110) surfaces, deposited at 80K with subsequent annealing, has been investigated at room temperature by means of scanning tunneling microscopy. Constant-current topographies, taken during 24 days, t
