A feasibility study towards ultra-thin PV solar cell devices by MOCDV based on a p-i-n structure incorporating pyrite [PDF]
FeSx layers were deposited onto aluminosilicate glass substrates over a temperature range of 180°C to 500°C using a horizontal AP-MOCVD reactor. Fe(CO)5 was used as the Fe source in combination with t-Bu2S2 or t-BuSH as S precursor to control the rate of

Infrared spectra of some sulfides and their analogs of binary composition in the long-wave region [PDF]
The far infrared spectra (500-60/cm) of some simple sulfides and their analogs were studied. In all, 22 minerals with different structure types were investigated, out of which 14 are sulfides (galena, alabandite, pyrrhotite, sphalerite, wurtzite ...

Effects of the expansion mechanisms on the pyrrhotite-induced deterioration of concrete foundations
Using pyrrhotite containing aggregates in concrete foundations can lead to premature deterioration visibly identifiable by extensive map cracking, expansion and deformation of the concrete foundation.

Identifying Framboidal Pyrrhotite: A Proxy for Hydrothermal Alteration of Organic‐Rich Sediments
Framboidal pyrrhotite, in sharp contrast to framboidal pyrite, has been rarely reported, and its formation remains poorly understood. Here we report its clear identification in a shale‐gas well core and explore its potential as a proxy for diagenesis or ...
