Þegar agnir eru smækkaðar niður á örsmæðar stærðarkvarða breytist ljós- og raf-hegðunþeirra. Til að rannsaka þessa hegðun voru samsetningar sem innihalda SiGe öragnirframleiddar með segulspætun og hitameðhöndlaðar í framhaldinu. Hitameðhöndlunin varframkvæmd við mismunandi hita og tíma í tvennskonar búnaði; a) hefðbundnum ofni með viðnámshitun og b) flass-hitun. Sýnin voru svo greind með röntgen bylgjubognun til að ákvarða fasa, efnis uppbyggingu. Ljómunarróf sýnana voru rannsökuð með tilliti til efnissamsetningar og mismunandi hitameðhöndlunar. Ljómunarrófin sýna svörun milli 450 og 900 nm þar sem fjölda toppa orsakast af staðbundnum orkuþrepum við samskeytiefnana, ásamt stærðar tengdum áhrifum frá örögnum í sýnunum.Nanoparticles display ...
