Electron energy loss spectroscopy (EELS) was used to study the absorption edge of various types of fused silica. The relationships between transmission (%T), fictive temperature (Tf), band gap energy (E0), and slope of the Urbach tail (K) were invest

A top-bottom effect in double diffraction has been observed in selected-area diffraction (SAD) patterns recorded from epitactic overgrowths. In SAD patterns recorded from epitactic α-Fe2O3 islands grown on an (0001) Al2O3 substrate, the double-diffr

The interface structure of α-Fe2O3 islands grown directly on an electron transparent Al2O3 (1102) substrate by low-pressure chemical vapour deposition has been characterized by weak-beam imaging in the transmission electron microscope. The islands e

Misfit dislocation networks at the Fe2O3-Al2O3 (0001) interface have been characterized using weak-beam imaging in the transmission electron microscope. The heterojunctions were prepared by chemical vapour deposition of α-Fe2O3 (haematite) directly

Continuous α-Fe2O3 films grown on bulk (0001)Al2O2 substrates by low-pressure chemical vapor deposition have been studied by transmission electron microscopy and the observations compared to those obtained from discontinuous films at an earlier stag

The early stages of growth of haematite (α-Fe2O3) on four orientations of sapphire (α-Al2O3), namely (0001), {102}, {110} and {100}, has been studied by transmission electron microscopy. Specimens were made by a new technique in which the haematite

The ability to tailor thin film interface structure is illustrated by the growth of thin ferric oxide films using different deposition parameters. Low-pressure chemical vapor deposition (CVD) has been used to grow α-Fe2O3 on sapphire while pulsed-la

Defects in thin films are often introduced at the substrate-film interface during the early stages of growth. The interface structures of semiconductor heterojunctions have been extensively studied because of the electrical activity of defects in the
