“…We can see from (6) and (7) that in order to use this method effectively we need information on the spatial electron density profile. If we assume that the electron density profile has cylindrical symmetry and the r and z dependences can be separated, n,, can be written as n,.…”

“…It was first described in 1970 by Lisitano and coworkers [216], who built a very similar discharge source for gases, but to this author's knowledge this is the first time such a structure has been coupled to the exit orifice of an effusion cell. Although the cavity may be resonant prior to ignition of the plasma, its modes are significantly perturbed by the plasma itself, a problem previously addressed analytically by Agdur and Enander [217].…”

This project was initiated after the Boeing Company decided to terminate its photovoltaic research and development efforts, and donated some research equipment to UF. Billy Stanbery, who was part of the Boeing team, decided then to enroll at UF to pursue a Ph.D degree. As such these events constituted a rare direct technology transfer from industry to a university. This helped to preserve more than the published legacy of the solar cell efforts at Boeing, and jump-started a comprehensive, multifaceted, and multidisciplinary copper indium diselenide solar cell research effort at UF. 5-15 Micro-Raman scattering spectra of islands on two indium-rich CIS films grown on GaAs (100). The uppermost curve is from an island "pool" on a sodium-dosed film and the lower two are single and averaged spectra from isolated islands on the sample without sodium shown in Figure 5- field. It focused primarily on the physical and opto-electronic properties of the general class of I-III-VI2 and II-IV-V2 compound semiconductors. More recent reviews specifically oriented towards CIS materials and electronic properties [2][3][4][5][6] are also recommended reading for those seeking to familiarize themselves with key research results in this field.There are also a number of excellent books and reviews on photovoltaic device physics [7,8], on the general subject of solar cells and their applications [9,10], and others specifically oriented towards thin-film solar cells [11,12] Researchers have not always been careful to reserve the use of the compound designation CuInSe2 for single-phase material of the designated stoichiometry, an imprecision that is understandable in view of the difficulty in discriminating CuInSe2 from some other compounds in this material system, as will be discussed in detail elsewhere in this treatise. The compound designations such as CuInSe2 will be reserved herein for reference to single-phase material of finite solid solution extent, and multiphasic or materials of indeterminate structure composed of copper, indium, and selenium will be referred to by the customary acronym, in this case CIS. 3 This review begins with an overview of the physical properties of the principal copper ternary chalcogenides utilized for PV devices, including their thermochemistry, crystallography, and opto-electronic properties. All state-ofthe-art devices rely on alloys of these ternary compounds and employ alkali impurities, so the physical properties and effects of these additives will be presented, with an emphasis on their relevance to electronic carrier transport properties. This foundation will provide a basis from which to address the additional complexities and variability resulting from the plethora of materials processing methods and device structures which have been successfully employed to fabricate high efficiency PV devices utilizing absorbers belonging to this class of materials.

“…48 However, with the emergence of microplasmas, the use of this diagnostic has been mostly overlooked. The microwave cavity method may be an ideal diagnostic for measuring the properties of microplasmas, since a microwave cavity can be made into almost any arbitrary shape and a number of electromagnetic modes can be excited.…”

A hollow-cathode microplasma modified the lumenal surface of small-diameter polyethylene (PE) tubing. A microwave cavity diagnostic was used to measure the density of the microplasma. Plasma light output was observed with a monochromator at various positions along the PE tube to assess uniformity. Treatment effectiveness was evaluated by measuring the variation in capillary rise at various positions along the tubing. A correlation between the properties of the inner surface of the PE tubing and the emitted light intensity was found. A poly(ethylene oxide) surfactant was immobilized to the lumenal surface of the PE tubing with an argon microplasma discharge. To test hematocompatibility, an in vitro blood-flow loop circulated heparinized human blood through both a plasma-treated and -untreated PE tubes, simultaneously. After blood exposure, the tubes were examined with a scanning electron microscope to assess the density of adhering platelets along the length of the tubes. By modifying the plasma parameters, the uniformity of the microplasma treatment along the tubing can be optimized.
