Abstract
The compounds BeO, BeS, MgO, MgS and Li2O are evaporated by electron bombardment and condensed onto substrates at low temperatures. Their infrared lattice vibration is measured between 10 and 42μ at different temperatures. Also Debye-Scherrer-diagrams are sketched for investigating the structure of the layers.
All substances without MgS are crystalline after condensation. They have a high degree of disorder which does not disappear during heating up to 293°K. Only MgS shows an amorphous phase. The crystallization of MgS-layers occurs at 293°K. Besides the normal cubic modification a new hexagonal phase can be found. The infrared spectra of all three phases are discussed.
Furthermore MgO- and Li2O-layers are prepared by burning metal flakes and precipitating the oxyde smoke onto substrates. The characteristic infrared absorption of such layers is interpreted by a theory ofFröhlich.
