Surface chemical characterization and surface diffraction effects of real margarite (001): An angle-resolved XPS investigation
surface of natural pure margarite angle-resolved XPS investigation real margarite (001)
<

The (001) surface of natural pure margarite was chemically characterized by angle-resolved X-
ray photoelectron spectroscopy (ARXPS). The extreme surface sensitivity of ARXPS permits con-
cluding th...
