Photon emission from polycrystalline silver induced by scanning tunneling microscopy is studied for three different tip materials (Au, PtIr and W). Photon emission intensity curves as a function of the tip voltage are observed to be almost identical

Thin layers of Bi2Te3 60 nm thickness were prepared by laser ablation in vacuum using KrF excimer laser. The energy of laser varied from 300 to 680 mJ and the laser energy density from 2 to 10 J cm–2. The substrate temperature varied for different

A way in which thin films of hydrogenated amorphous silicon (a-Si: H) can be instantaneously crystallized at room temperature is reported. The metal-induced solid-phase crystallization (MISPC) method with nickel surface coverage is used. In compariso

Thin films of Er:YAG and Er:YAP were deposited by subpicosecond (450 fs) and nanosecond (20 ns) KrF laser (λ=248 nm) on YAG, YAP, fused silica, silicon and sapphire substrates. Laser spot size, energy density, substrate temperature and deposition am

A hexagonal modification (P63mc) of (NH4)2SiF6 was grown accidentally. This new modification has the unit-cell c parameter doubled with respect to a previously reported trigonal form (P\overline 3m1) of the title compound. The H atoms in the present
