Scanning electron acoustic microscopy observations of twins and grain boundaries in III‐V materials Domínguez-Adame Acosta, Francisco Piqueras De Noriega, Francisco Javier 538.9 Physics Applied Física de materiales © American Institute of Physics. This work has been supported by the Volkswagen Foundation and by the Comisión Intermiisterial de Ciencia y Tecnología (Project No. PB86-0151). Polycrystalline GaP and InP have been observed by scanning electron acoustic microscopy. While grain boundaries show a weak contrast, twinned regions are clearly revealed. Results suggest that the contrast observed is related to signal generation by a piezoelectric‐coupling mechanism Volkswagon Foundation Comision Interministerial de Ciencia y Tecnología Depto. de Física de Materiales Fac. de Ciencias Físicas TRUE pub 2023-06-20T19:08:30Z 2023-06-20T19:08:30Z 1989-09-15 journal article https://hdl.handle.net/20.500.14352/59303 0021-8979 10.1063/1.344198 eng PB86-0151 open access application/pdf American Institute of Physics
