“…In the third method, we assumed that all ions were parents and ion intensities were used to calculate partial pressures of the hypothetical gaseous precursors E 10"8 with Eq. [2] and [3]. This assumption had the effect of F~ removing summations over j, there being but one ion from each precursor.…”

“…rial reported so far does not give consistent results in the low doping range. This is because of the strong dependence of the doping on the initial Cr content in the substrate material (3). Moreover, the experimental data available in the literature are not systematic enough for the purpose of constructing a theoretical model.…”

“…The study of indium telluride is of interest because of its application in solid-state devices: nuclear radiation detectors (1), photoconductors (2), and heterojunction devices (3)(4). Knowledge of the chemistry and thermodynamics of the gas phase over indium tellurides will be useful in the preparation of such devices by vapor-phase growth.…”

The vapor phase over normalInTefalse(1false) at 1106±2K was analyzed by an isothermal total exhaustion experiment with a Knudsen‐cell mass spectrometer. In+, In2+ , Te+, Te2+ , InTe+ , In2Te+ , InTe2+ , and In2Te2+ were observed. The appearance potentials of In+, In2+ , Te+, InTe+ , In2Te+ , InTe2+ , and In2Te2+ were 7.7, 9.6, 9.9, 8.6, 8.3, 8.2, and 7.6V, respectively, with an uncertainty of 0.3V. The fragment ions and their precursors were identified in three ways: (i) their appearance potentials were compared with those in the literature; (ii) the slopes of the plots of ionic intensities vs. time were compared; and (iii) all ions were assumed to be parents; hypothetical equilibrium constants for several vapor‐phase reactions involving the hypothesized gaseous precursors were checked for time‐dependent trends and, where possible, compared with literature data. From these three tests, we found that almost all of In+, In2+ , Te+, InTe+ , and In2Te+ came from In2normalTefalse(normalgfalse) , almost all of Te2+ came from Te2false(normalgfalse) , and almost all of InTe2+ and In2Te2+ came from In2Te2false(normalgfalse) . Thus, it was found that the vapor phase was composed of Te2false(normalgfalse) , In2normalTefalse(normalgfalse) , and In2Te2false(normalgfalse) . The mass spectrometer was calibrated with integrated ion intensities and the analysis of the fragmentation processes. Partial pressures of the vapor species were derived from ionic intensities. The equilibrium constant for the reaction2In2normalTe)(normalg+Te2)(normalg=2In2Te2)(normalgwas found to be false(1.81±0.10false)×10−3 Pa−1 . The standard enthalpy of the above reaction at 298 K was −310.9±0.5 normalkJ .

“…The Newvicon| family of tubes is based on a complex mixture of microcrystalline zinc cadmium telluride on a zinc selenide base (23)(24)(25)(26) and was developed by Matsushita. The different versions of this photoconductor are made by varying the constituent profile of this material throughout its thickness to achieve the desired characteristics.…”

This article surveys the various photoconductors currently used in beam-scanned and Vidicon-type television tubes. The chemical, physical, and electronic characteristics of the photoconductors are described, as well as the way they are utilized in the camera tube to produce a television signal. The various materials discussed are selenium, antimony trisulfide, lead oxide, cadmium selenide, zinc cadmium telluride, zinc sulfide, and silicon, all of which have been used as the basis for these photoconductors.
