Hydrogen induced optically-active defects in silicon photonic nanocavities.
We demonstrate intense room temperature photoluminescence (PL) from optically active hydrogen- related defects incorporated into crystalline silicon. Hydrogen was incorporated into the device layer of a silicon on insulator (SOI) wafer by two methods: hydrogen plasma treatment and ion implantation. The room temperature PL spectra show two broad PL bands centered at 1300 and 1500 nm wavelengths:...
متن کاملAre lignins optically active?
The accepted derivation of lignins from non(enzymatically)-controlled radical coupling reactions has been recently challenged, and it is relevant to ascertain unequivocally whether lignins are or are not (as normally assumed) optically active. Two approaches were used. First, DFRC (derivatization followed by reductive cleavage) dimers derived from beta-5- and beta-beta-units in pine lignins, wh...
متن کاملSpontaneously forming 30-150Å Defects at the Si/oxide interface
A previously perforated planar TEM specimen of silicon sample (8GLJH-060) was ion milled for 10s using two argon guns at an angle of 20°, 0.5mA per gun and a fixed voltage of 4kV. The time the specimen surface was in contact with air was minimized to 3min, by taking it out of the ion mill and putting it in the electron microscope airlock immediately afterwards. The silicon wafer was left in the...
متن کاملRefraction at the Interface of a Lossy Metamaterial
The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...
متن کاملOptically active diaryl tetrahydroisoquinoline derivatives.
In (1R,3S)-6,7-dimethoxy-3-(methoxydiphenylmethyl)-1-phenyl-1,2,3,4-tetrahydroisoquinoline, C(31)H(31)NO(3), (I), and (1R,3S)-2-benzyl-3-[diphenyl(trimethylsiloxy)methyl]-6,7-dimethoxy-1-phenyl-1,2,3,4-tetrahydroisoquinoline, C(40)H(43)NO(3)Si, (II), the absolute configurations have been confirmed to be R and S at the isoquinoline 1- and 3-positions, respectively, by NMR spectroscopy experiment...
