RT Journal Article T1 Temperature-dependence of scanning electron acoustic microscopy signal in MgO and SIC A1 Urchulutegui, M. A1 Piqueras De Noriega, Francisco Javier AB The variation of the electron acoustic signal as a function of temperature in ceramic materials has been studied. Scanning electron acoustic microscopy (SEAM) contrast in MgO single crystals and in reaction bonded SiC, between 100 and 273 K, is discussed and compared. SEAM signal and contrast have been found to be temperature dependent in both materials as a consequence of the temperature dependence of several material parameters.
