Impurity spectrum
Witryna15 gru 1994 · Most chemical vapor deposited (CVD) diamond films contain impurities which increase their optical absorption in the regions of desired transparency. This paper examines the incorporation of these impurities, intentional or otherwise, and their effect on the IR absorption of CVD diamond, particularly in the 8–12 and 3–5 μm regions.

Witryna29 cze 2005 · A great advantage of qHNMR is that, in the case of non-characterized impurities, the spectrum yields also a lot of structural information about the impurity. A complete qHNMR analysis of a sample demands 1–2 h, or even less if the protocol is well-validated, including 10–30 min spectrometer time. Witryna13 cze 2008 · We investigate the impurity resonant state induced by nonmagnetic impurities in d -wave cuprate superconductors in two different impurity models: (i) in a pure potential scattering model within the T -matrix approach and (ii) in a Bose–Fermi Kondo model within the large- N formalism.
