- Spectroscopic characterization of bismuth embedded Y zeolites
[作者:Sun, HT; Sakka, Y; Miwa, Y; Shirahata, N; Fujii, M; Gao, H,期刊:Applied Physics Letters, 页码:131908-131908 , 文章类型: Article,,卷期:2010年97-13]
- Bismuth embedded Y zeolites were studied by using UV-vis-near infrared (NIR) diffuse reflectance, Raman, and steady-state NIR photoluminescence spectroscopy. The results suggest that Bi-5(3+) and Bi+ active centers coexi...
- Straining of SiGe ultrathin films with mesoporous Si substrates
[作者:Boucherif, A; Blanchard, NP; Marty, O; Regreny, P; Guillot, G; Grenet, G; Lysenko, V,期刊:Applied Physics Letters, 页码:131910-131910 , 文章类型: Article,,卷期:2010年97-13]
- We report on the fabrication and characterization of ultrathin (down to 50 nm) tensile strained SiGe films on mesoporous Si substrates. Low temperature oxidation of the porous substrate relaxes the compressive strain in ...
