Nanotechnology Unit

NANOTECHNOLOGY UNIT

The Nanotechnology Unit of the Nanomaterials and Nanotechnology Center was inaugurated on July 2005, and it is located at the Severo Ochoa building of the Scientific - Technical Services in the “Campus del Cristo” of University of Oviedo.

The Nanotechnology Unit offers a wide range of nanofabrication services for nanostructured materials and devices and is focused on two main areas:

• Fabrication of micro and nanostructures using optical and electron beam lithography techniques

• Characterization of micro-and nanostructures at the nanoscale using scanning microscopy techniques.

Services Offered

Scanning Probe Microscopy

• Scanning Tunneling Microscopy (STM) with pseudo-atomic resolution on metallic surfaces.

• Atomic Force Microscopy (AFM): characterization of the roughness and detection of up to monoatomic steps on metallic or insulating surfaces, observation of biological samples, and characterization of the solid-liquid interface in liquid cell.

• Magnetic Force Microscopy (MFM) for the observation of magnetic domains.

• Lithography by local oxidation on Si substrates.
