We present a systematic study of the local hydrogen bonding in hydrogenated polymorphous silicon thin films (pm-Si:H), a heterogeneous material deposited on the edge of crystallinity, by means of Fourier transform infrared spectroscopy. A vibrational mode ...
When silicon thin films are deposited by plasma enhanced chemical vapor deposition in a plasma regime close to powder formation, a new type of material, consisting of an amorphous matrix in which silicon nanocrystallites are embedded is obtained. This mate ...
A novel Silicon Sacrificial Layer Dry Etching (SSLDE) technique using sputtered amorphous or LPCVD polycrystalline silicon as sacrificial layers and a dry fluorine-based (SF₆) plasma chemistry as releasing process is reported with a detailed experimental s ...
Using a first-principles approach, we compare calculated core-level shifts with experimental data for amorphous carbon at different densities. We used a molecular dynamics approach based on an environmental-dependent tight-binding (EDTB) Hamiltonian to gen ...
The tribological behavior of carbon based thin films is strongly influenced by their chemical composition, polycrystalline structure and surface morphology. We present friction measurements on laser deposited amorphous carbon and carbon nitride (CNchi) thi ...
Infrared (IR) absorption spectroscopy and mass spectrometry have been simultaneously applied to dusty radiofrequency (RF) plasmas in methane, acetylene and ethylene. The combination of IR absorption spectroscopy and mass spectrometry allows the chemical co ...
We present the results of a crystallization study on NiTi shape memory thin films in which amorphous films are annealed by a scanning laser. This technique has the advantage that shape memory properties can be spatially distributed as required by the appli ...
Nanocomposite thin films exhibit interesting optical properties which differ from those of the pure constituents. Effective medium theories are used to model the dielectric function of the nanocomposite materials. We give an introduction to the theories of ...
C60 fullerene reacted with phosphorus at high temperatures to graphitic materials with strongly differing properties. Several spectroscopic investigations as Raman, ESR, XPS and 31P-NMR as well as TEM and ESEM have shown that the structural order of the mo ...
A review. Although the synthesis of beta -lactams by means of tethered Ugi reactions was known since the early 1960s, the 1995 report from Ugi's group could be regarded as a turning point in the development of novel multicomponent reactions (MCRs) for hete ...
