An Investigation Of The Thermo- And Action- Electric Properties Of Molybdenite, William Otis Johnson
An Investigation Of The Thermo- And Action- Electric Properties Of Molybdenite, William Otis Johnson
Master's Theses
Considerable work has been done on various mineral substances and chemical compounds within recent years to ascertain, if possible, whether the substance possessed any degree of photo- or thermos-sensitivity; and, to determine the characteristics of these responses. Among the most prominent substances which have been tested are selenium, bismuth, antimony, hematite, stibnite, and molybdenite. It was the purpose of this investigation to summarize the phenomena that have occurred within samples of molybdenite under a variety of conditions involving heat, light, and e.m.f.

Actino- And Thermo- Response Of Molybdenite In Vacuo With Various Colored Lights., John H. Fulton
Master's Theses
The purposes of this investigation are to study the reaction of molybdenite cells to light of various colors while in vacuo and at various temperatures. The samples of molybdenite were also subjected to radiant heat in the last part of the experiment, which was undertaken to determine to some extent the amount of thermos-electric effect which was due to thermal radiation in the first part of the investigation.
