Wednesday, June 22, 2011. Which and how many parameters can be simultaneously determined depends upon the type of experiment performed. The CMMP ellipsometer is what is called a nulling single wavelength ellipsometer. To the sample surface, and a p-component. What is measured in ellipsometry is the parameter, rho.

Thursday, June 16, 2011. Friday, June 10, 2011. The scanning profilometer is a complement to SEM. Fast; very large scan lengths; very larg.

Wednesday, June 11, 2014. In XPS, unlike Auger spectroscopy where the kinetic energy. Of electrons is presented, the binding energy. In this case, the kinetic energy of the photoelectrons is measured by the analyzer and then converted to binding energy by referencing to the energy of the X-ray excitation source.

Wednesday, March 19, 2014. Simple texture analysis is possibly by comparing coupled θ-2θ scans with a standard that is known to be without texture or preferred orientation. This probe of preferred orientation only addresses texture perpendicular to the sample surface, so a more in depth texture study will require a texture cradle. Tuesday, July 2, 2013. In high-temperature XRD the sample is glued to a Pt-ribbon that acts as the sample holder as well as heater using.

Friday, October 25, 2013. One constraint is that samples must fit the 7 mm coaxial wave guide. Solid materials such as the telfon shown in this picture, can be machined to a 3 mm ID and 7 mm OD to tightly fit the coaxial guide. Deviations from the optimal ID and OD will require gap corrections. Powder samples need to be cast into torroids by mixing with wax or a resin.

Wednesday, October 1, 2014. Because of staffing limitations at the CMMP facility, services requiring CMMP staff may involve some delay. In general, services are provided on a first-come first-serve basis,. Users are encouraged to receive training if they intend on being regular users.
