- Directional elliptically polarized terahertz emission from air plasma produced by circularly polarized intense femtosecond laser pulses - art. no. 161505
[作者:Jahangiri, F; Hashida, M; Tokita, S; Nagashima, T; Hangyo, M; Sakabe, S,期刊:Applied Physics Letters, 页码:61505-61505 , 文章类型: Article,,卷期:2011年99-16]
- We have observed directional elliptically polarized terahertz (THz) waves emitted from air plasma produced by circularly polarized femtosecond laser pulses. The spatial distribution of the THz waves shows that the radiat...
- Temperature dependent energy level shifts of nitrogen-vacancy centers in diamond - art. no. 161903
[作者:Chen, XD; Dong, CH; Sun, FW; Zou, CL; Cui, JM; Han, ZF; Guo, GC,期刊:Applied Physics Letters, 页码:61903-61903 , 文章类型: Article,,卷期:2011年99-16]
- Magnetic resonance and fluorescence spectra of nitrogen-vacancy (NV) color centers ensemble in high purity diamond sample were measured, with temperature ranging from 5.6 K to 295 K. Both microwave and optical transition...
- Three-photon near-infrared quantum splitting in beta-NaYF4:Ho3+ - art. no. 161904
[作者:Yu, DC; Huang, XY; Ye, S; Peng, MY; Zhang, QY; Wondraczek, L,期刊:Applied Physics Letters, 页码:61904-61904 , 文章类型: Article,,卷期:2011年99-16]
- We report on three-step sequential three-photon near-infrared (NIR) quantum splitting in beta-NaYF4:Ho3+, where one absorbed ultraviolet photon is split into three NIR photons with wavelengths 850, 1015, and 1180 nm. The...
- Hug-like island growth of Ge on strained vicinal Si(111) surfaces - art. no. 161907
[作者:Persichetti, L; Menditto, R; Sgarlata, A; Fanfoni, M; Balzarotti, A,期刊:Applied Physics Letters, 页码:61907-61907 , 文章类型: Article,,卷期:2011年99-16]
- We examine the structure and the evolution of Ge islands epitaxially grown on vicinal Si(111) surfaces by scanning tunneling microscopy. Contrary to what is observed on the singular surface, three-dimensional Ge nanoisla...
- Electrical spin injection and detection at Al2O3/n-type germanium interface using three terminal geometry - art. no. 162102
[作者:Jain, A; Louahadj, L; Peiro, J; Le Breton, JC; Vergnaud, C; Barski, A; Beigne, C; Notin, L; Marty, A; Baltz, V; Auffret, S; Augendre, E; Jaffres, H; George, JM; Jamet, M,期刊:Applied Physics Letters, 页码:62102-62102 , 文章类型: Article,,卷期:2011年99-16]
- In this letter, we report on electrical spin injection and detection in n-type germanium-on-insulator using a Co/Py/Al2O3 spin injector and 3-terminal non-local measurements. We observe an enhanced spin accumulation sign...
- Diffusion of tin in germanium: A GGA+U approach - art. no. 162103
[作者:Tahini, H; Chroneos, A; Grimes, RW; Schwingenschlogl, U,期刊:Applied Physics Letters, 页码:62103-62103 , 文章类型: Article,,卷期:2011年99-16]
- Density functional theory calculations are used to investigate the formation and diffusion of tin-vacancy pairs (SnV) in germanium (Ge). Depending upon the Fermi energy, SnV pairs can form in neutral, singly negative, or...
