RT journal article T1 High resolution boron content profilometry at δ-doping epitaxial diamond interfaces by CTEM A1 Piñero Charlo, José Carlos A1 Lloret Vieira, Fernando Manuel A1 Alegre Salguero, María de la Paz A1 Villar Castro, María del Pilar A1 Fiori, Alexandre A1 Bustarret, Etienne A1 Araújo Gay, Daniel A2 Ciencia de los Materiales e Ingeniería Metalúrgica y Química Inorgánica A2 Didáctica A2 Física Aplicada AB Ultimate spatial resolution in boron δ-doped homoepitaxial diamond interfaces has been achieved by diffraction contrast technique in Transmission Electron Microscopy. The combination of two reflections with the Howie-Whelan equations allows profiling the boron content of δ-doped diamond homoepitaxial layers by fitting experimentally measured CTEM intensities with the theoretical ones. To validate the method, the obtained doping profiles are compared with that of secondary ion mass spectrometry, obtaining a boron concentration of 1.6·1021 at/cm−3, which is in good agreement with that of SIMS. This approach is capable to perform dopant concentration quantification in a non-destructive way, and provides the possibility of nanometric resolution dopant concentration mapping by TEM PB Elsevier SN 0169-4332 YR 2018 FD 2018-12-15 LK http://hdl.handle.net/10498/30438 UL http://hdl.handle.net/10498/30438 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 11-nov-2026
