By correlating speckle patterns collected at the (001) anti-Bragg position we are able to measure surface dynamics when the averaged incoherent x-ray scattering appears static. In the temperature range above the rotational epitaxy transition and below the roughening transition (1750 K - 1830 K), we have observed well-defined oscillatory autocorrelations of speckles that persist for tens of minutes, in addition to the expected thermal dec","authors_text":"A.
