Animação feita pelo Imaging Technology Group do Beckman Institue da Universidade de Illinois mostrando os conceitos básicos de um SPM e as três principais modalidades: STM, AFM de contato e AFM de contato intermitente.
Vídeo interessante sobre a instalação de um modelo compacto de um
microscópio de forca atômica. É bom de se ver detalhes do equipamento.
Easy to use scanning tunneling microscope to image conducting surfaces
and to investigate effects and characteritics on atomic and molecular
scale. A variety of experiments in the fields of Material Sciences,
Solid State Physics/Chemistry, Nanotechnology and Quantum Mechanics can
be performed. For example: micro- and nano morphology of surfaces, nano
structures, imaging of atoms and molecules, conductivity, tunneling
effect, charge density waves, single molecule contacts, and
nanostructuring by self organisation (self assembled monolayers).
Benefits:
*
Out-of-the-box-device incl. all necessary accessories for a prompt
entry into the world of atoms and molecules * Portable and compact:
transportable, easy to install with a small footprint * Single device
for more stable measurements * Quick atomic resolution on a normal
table. No need for expensive vibration isolation * Easy to use: Ideal
for nanotechnology education, preparing students for their work on
high-level research devices, and outreach * Accessible sample stage and
scanning tip: Quick exchange of tip and sample * Low operating voltage:
Safe for all users
