Magnetite thin films [PDF]

, 1972
A low temperature process for converting hematite (α-Fe_2O_3) thin films into magnetite (Fe_3O_4) is described. The films produced are unambiguously identified as magnetite by several complementary methods of analysis.

Synthesis of Alkaline Earth Diazenides MAEN2 (MAE = Ca, Sr, Ba) by Controlled Thermal Decomposition of Azides under High Pressure [PDF]

, 2012
The alkaline earth diazenides MAEN2 with MAE = Ca, Sr and Ba were synthesized by a novel synthetic approach, namely, a controlled decomposition of the corresponding azides in a multianvil press at highpressure/ high-temperature conditions.

Hidden Diradical: Conformational Switch for Solvatochromic NIR Emission With Unity Quantum Yield in Thiele's Hydrocarbon

Angewandte Chemie, EarlyView.
Halogen substitution controls a conformational switch between a folded closed‐shell and a flat singlet‐diradical conformer in an air‐stable Thiele‐diradical. This conformational switch allows for near‐unity photoluminescence quantum yield with a large Stokes shift, solvatochromism, and a long‐lived excited state.

Mössbauer diffractometry on polycrystalline (57)Fe3Al [PDF]

, 2002
A Mossbauer powder diffractometer was used to measure diffraction patterns from polycrystalline foils of (Fe3Al)-Fe-57. The intensities of Bragg diffractions were measured as a function of the energy of the incident photon.

SiGeC alloy layer formation by high-dose C + implantations into pseudomorphic metastable Ge0.08Si0.92 on Si(100) [PDF]

, 1997
Dual-energy carbon implantation (1 × 1016/cm2 at 150 and at 220 keV) was performed on 260-nm-thick undoped metastable pseudomorphic Si(100)/ Ge0.08Si0.92 with a 450-nm-thick SiO2 capping layer, at either room temperature or at 100 °C.

Resistive Heating for Inducing Localized Crystal Growth in Organic Thin Film Devices

Advanced Materials Technologies, EarlyView.
Rubrene thin films are promising for organic optoelectronics due to high hole mobility. However, uncontrolled crystallization and grain boundaries from standard thermal processing hinder lateral device scalability. This work presents femtosecond‐laser micromachining and patterned resistive heating to induce localized, deterministic crystallization ...
