The NanoESCA offers chemical state mapping with unsurpassed XPS lateral resolution (<500 nm achieved under laboratory conditions). The instrument allows analyzing smallest sample structures giving chemical state information beyond the limits of other high lateral resolution techniques such as scanning Auger and TOF SIMS.
Real time sample navigation is ensured by PEEM technique which operates in the secondary electron regime. The PEEM mode allows finding small features easily on a large sample area and provides high resolution (< 50 nm resolution). In addition the PEEM mode provides quantitative information on the very local work function and local sample charging.
The spectroscopy capabilities of the NanoESCA can be completed by the ARUPS option which allows analyzing the k-space from m-areas e.g. small grains in a polycrystalline surface with ultimate angular acceptance.
For its revolutionary design the NanoESCA received the 2007 R&D 100 award.
