Electrical properties of vitreous Tl2Te·As2Te3

Journal of Non-Crystalline Solids, 1970
Abstract Combined measurements of electrical resistivity, Hall effect and thermoelectric power have been performed on vitreous Tl2Te·As2Te3 as a function of temperature. The resistivity and Hall coefficient both vary exponentially with temperature in the range 125–325°K.

Characterization of retinal tissue and vitreous humor with Electrical Impedance Spectroscopy

2017 8th International IEEE/EMBS Conference on Neural Engineering (NER), 2017
Electrical impedance spectroscopy is used to study the retina and the vitreous humor which can help in designing retinal stimulation experiments. Electrical stimulation of retina is done to artificially stimulate retinal neurons for restoring vision in blind patients. The stimulus is given through microelectrodes which are placed over the retina. Since

Electrical Conductivity of Vitreous GeO2

Journal of Applied Physics, 1972
Electrical-conductivity measurements were carried out on vitreous GeO2 and the conductivity was measured as a function of frequency and temperature in the following ranges: 1.5 Hz ≤ ν ≤ 108 Hz and − 180°C ≤ T ≤ 600°C. The results are discussed in terms of a phenomenological Debye theory, and it is concluded that the conductivity is due to ionic ...

Electrical and Optical Properties of Vitreous Selenium

Physical Review, 1963
The space-charge limited current-voltage characteristics of evaporated layers of vitreous selenium from 2.4 to 60 \ensuremath{\mu} thick are described. It is shown that both an exponential and a Gaussian distribution of states will explain these characteristics. An analytic solution is derived for the case of the exponential distribution of states: $N(\

Origin of the electrical activity of iron atoms in vitreous arsenic selenide

Glass Physics and Chemistry, 2016
Iron atoms in vitreous arsenic selenide films form single electron donor centers, while the Fermi level shifts from the middle of the band gap to the bottom of the conduction band with an increase in the iron concentration due to the filling of single electron states of the acceptor type located below the Fermi level.

Electrical conduction in the vitreous and crystallized Li2O–V2O5–P2O5 system

Solid State Ionics, 2010
Abstract The glass-forming region of the Li 2 O–V 2 O 5 –P 2 O 5 system was examined. The glass transition temperature and stability of glass were enhanced with increasing P 2 O 5 content. Li 2 O–V 2 O 5 –P 2 O 5 glasses show electronic or ionic conduction depending on the glass composition.
