Direct writing of metal features narrower than 100 nm is accomplished by scanning a focused ion beam over a substrate covered with a thin solid metalorg. film. A metalorg. cluster coordination compd. [Ir4(CO)11Br] [N(C2H5)4] is spun on an oxidized Si wafer ...
An argon laser is used to induce Laser Chem. Vapor Deposition (LCVD) of platinum using platinum bihexafluoroacetylacetonate as precursor. The process can be photolytic or pyrolytic depending on the laser power used. These processes are studied by recording ...
A 351-363 nm wavelength argon laser is used to induce pyrolytic laser chem. vapor deposition of platinum, using platinum bishexafluoroacetylacetonate as a precursor. The deposit thicknesses and diams. are presented according to exposure time, precursor pre ...
Low pressure CVD of Cu from its bis-hexafluoroacetylacetonate was studied on oxidized Si substrates locally seeded with a 2.5 .ANG. Pt prenucleation film. ...
A self-consistent discontinuum theory describing the dependence of the diffuse reflectance and diffuse transmittance of powders on their optical absorption coeff. is presented. The theory is valid for particle sizes large compared to the exciting wavelengt ...
The efficacy of photodynamic therapy (PDT) alone was evaluated on 41 ‘early’ squamous cell carcinomas of the pharynx (10), oesophagus (15) and tracheo-bronchial tree (16). All lesions but two were synchronous second primaries in ENT-patients suffering from ...
The rate of photolytic laser chem. vapor deposition (LCVD) of Pt from its bishexafluoroacetylacetonate precursor is measured as a function of the light intensity, the wavelength, the precursor pressure, and the laser beam diam. at the surface. The waveleng ...
A novel anal. technique, Fourier-transform IR photopyroelec. spectroscopy (FT-IR-P2ES) is demonstrated and applied to spectroscopic investigations of solid materials. The salient features of the technique and its advantages over other conventional FT-IR ph ...
The photodissocn. I2M + hn -> I2 + M was studied for M = C2H6 and M = (C2H5)2O with excitation above the dissocn. limit of I2B state. Vibrational population distributions of the I2(B) product mols. are reported. The results are compared to previous studies ...
