Air-Stable Transparent Silver Iodide–Copper Iodide Heterojunction Diode

ACS Applied Materials & Interfaces, 2017
Transparent AgI-CuI heterojunctions with high rectifying diode behavior were prepared via vapor-phase iodization of metal thin films on transparent conducting oxide substrates. At room temperature, Ag and Cu metal thin films were quickly transformed into the transparent and well-crystallized β-phase of AgI and the γ-phase of CuI, respectively.

The Silver Iodide–Thallium Iodide Pseudo-Binary System

Physica Status Solidi (a), 1983
A form of the T−x section of the equilibrium phase diagram for the system AgI–TlI is proposed on the basis of thermal and X-ray diffraction data. Two room temperature stable intermediate phases AgTlI2, and AgTl2I3 are confirmed, and evidence is found for two other phases, stable at higher temperatures.

Ice Nucleation by Coprecipitated Silver Iodide and Silver Bromide

Science, 1971
The ability of silver iodide to cause freezing of supercooled water is improved if up to 30 percent of the iodine atoms in the crystal are replaced with bromine atoms.

Ice Nucleation Silver Iodide-Sodium Iodide: A Reevaluation

The Journal of Weather Modification, 2012
New, preliminary, laboratory studies of the 2Agl.Nal ice nucleus are being conducted in the CSU Isothermal Cloud Chamber. Rates and mechanisms of ice nucleation are investigated using chemical kinetic methodology. Interrelationships between ice nuclei effectiveness, rates and mechanisms of nucleation, and chemical composition are studied.

Electrical transport and phase stability in silver iodide—cadmium iodide

Physica Status Solidi (a), 1963
A form of the equilibrium diagram for the system AgICdI2 is proposed on the basis of thermal, X-ray diffractometer, and electrical conductivity data. Only one intermediate equilibrium phase, of composition Ag2CdI4, of tetragonal form with a0 = 6.35 A and c0 = 12.7 A is apparent; the previously reported hexagonal form of this composition being ...

Polytypism in silver iodide

Acta Crystallographica Section A, 1974
Synthetic crystals of silver iodide are shown to form polytypes other than the previously reported wurtzite-type β-AgI and sphalerite-type γ-AgI. Four new polytypes have been discovered and their layer sequences determined by X-ray diffraction. The constant of proportionality between percentage hexagonality and birefringence of AgI polytypes has been ...

Effect of pressure on ionic conductivity in rubidium silver iodide and silver iodide

Physical Review B, 1978
The effect of pressure on the ionic conductivity of Rb${\mathrm{Ag}}_{4}$${\mathrm{I}}_{5}$ and AgI has been measured, using single crystals and polycrystalline samples, up to pressures of 6 kbar. The activation volumes for motion in $\ensuremath{\alpha}\ensuremath{-}\mathrm{Rb}{\mathrm{Ag}}_{4}{\mathrm{I}}_{5}$ and $\ensuremath{\beta}\ensuremath ...

Investigations on silver iodide silver oxysalt glass ceramics

Solid State Ionics, 1996
Abstract Silver ion conductivity and microstructural changes during the crystallization process of the glass systems AgI-Ag 2 O-M x O y ( M = V , P , Mo , B ) have been investigated by impedance spectroscopy and high temperature X-ray diffraction.

Conductivity relaxation in silver iodide-silver borate glasses

Journal of Non-Crystalline Solids, 1991
Abstract Conductivity relaxation in ionically conducting glasses of composition (AgI) x (Ag 2 O:2B 2 O 3 )1−x, where x =0 and 0.6 has been studied. The complex capacitance was measured in the frequency range 10 −3 –10 6 Hz at temperatures for which the contribution of electrode polarisation to the dielectric response was found to be negligible.
