Experiments were done on Si29/Sinat heterostructures using neutron reflectometry and secondary ion mass spectrometry. The diffusivities follow the Arrhenius law in the temperature range between 550 and 700 °C with an activation energy of (4.4±0.3) eV. In comparison with single crystalline silicon the diffusivities are tremendously higher by 5 orders of magnitude at about 700 °C, which can be interpreted as the consequence of a high diffusion entropy.}, cin = {JCNS (München) ; Jülich Centre for Neutron Science JCNS (München) ; JCNS-FRM-II / JCNS-2 / PGI-4 / JARA-FIT}, ddc = {550}, cid = {I:(DE-Juel1)JCNS-FRM-II-20110218 / I:(DE-Juel1)JCNS-2-20110106 / I:(DE-Juel1)PGI-4-20110106 / $I:(DE-82)080009_20140620$}, pnm = {6G15 - FRM II / MLZ (POF3-6G15) / 6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)}, pid = {G:(DE-HGF)POF3-6G15 / G:(DE-HGF)POF3-6G4}, experiment = {EXP:(DE-MLZ)MARIA-20140101}, typ = {PUB:(DE-HGF)16}, UT = {WOS:000368281600006}, doi = {10.1103/PhysRevLett.116.025901}, url = {https://juser.fz-juelich.de/record/280702}, }
