- Effects of hydration levels on the bandwidth of microwave resonant absorption induced by confined acoustic vibrations
[作者:Liu, TM; Chen, HP; Yeh, SC; Wu, CY; Wang, CH; Luo, TN; Chen, YJ; Liu, SI; Sun, CK,期刊:Applied Physics Letters, 页码:173702-173702 , 文章类型: Article,,卷期:2009年95-17]
- We found the hydration levels on the capsid surface of viruses can affect the bandwidth of microwave resonant absorption (MRA) induced by the confined acoustic vibrations (CAV). By decreasing the pH value of solution dow...
- Two-dimensional growth of SrTiO3 thin films on (001) MgO substrates using pulsed laser deposition and reflection high energy electron diffraction

- Two-dimensional epitaxial growth of SrTiO3 is achieved on MgO, a substrate presenting a large lattice mismatch of 7.9%. In situ reflection high energy electron diffraction (RHEED) is used to monitor and control the growt...
- Resistance of diamond (100) to hyperthermal atomic oxygen attack
[作者:Shpilman, Z; Gouzman, I; Grossman, E; Shen, L; Minton, TK; Hoffman, A,期刊:Applied Physics Letters, 页码:174106-174106 , 文章类型: Article,,卷期:2009年95-17]
- The morphology of polycrystalline chemical vapor deposited (CVD) diamond films following the interaction with hyperthermal (similar to 5 eV) atomic oxygen (AO) was studied by atomic force microscopy. Selective etching of...
- Correlation of O (1s) and Fe (2p) near edge x-ray absorption fine structure spectra and electrical conductivity of La1-xSrxFe0.75Ni0.25O3-delta
[作者:Erat, S; Braun, A; Ovalle, A; Piamonteze, C; Liu, Z; Graule, T; Gauckler, LJ,期刊:Applied Physics Letters, 页码:174108-174108 , 文章类型: Article,,卷期:2009年95-17]
- A-site substitution of La3+ by Sr2+ in polaron conducting ABO(3)-type perovskite La1-xSrxFe0.75Ni0.25O3-delta causes oxidation of Fe3+ toward Fe4+ and formation of conducting electron holes, as evidenced by Fe (2p) and O...
- The surface activation layer of GaAs negative electron affinity photocathode activated by Cs, Li, and NF3
[作者:Sun, Y; Kirby, RE; Maruyama, T; Mulhollan, GA; Bierman, JC; Pianetta, P,期刊:Applied Physics Letters, 页码:174109-174109 , 文章类型: Article,,卷期:2009年95-17]
- The lifetime of GaAs photocathodes can be greatly improved by introducing Li in the Cs+NF3 activation process. The surface activation layer of such photocathodes is studied by synchrotron radiation photoemission and is c...
