Researcher: Ultrathin BaF2 films

"I had to explain to him that a thin film of barium fluorides with different thicknesses was deposited on GaAs substrate by electron beam evaporation. The aim of the work was to identify the best growth conditions for the production of coatings with a low work function suitable for the anode of hybrid thermionic-photovoltaic (TIPV) devices. The chemical composition and work function ϕ of the films with different thicknesses were investigated by X-ray photoelectron spectroscopy (XPS) and ultraviolet photoelectron spectroscopy (UPS). The lowest value of ϕ = 2.1 eV was obtained for the film with a thickness of ~2 nm. In the valence band spectra of the films at low kinetic energy, near the cutoff, a characteristic peak of negative electron affinity was present. This effect contributed to a further reduction of the film's work function. In 2007, I was involved in a project to develop a new type of solar cell based on nanostructured barium strontium titanate (BST) thin films deposited on Si substrates by pulsed laser deposition (PLD)."

Barium Fluoride (BaF2) Work functionThermionic-thermo photovoltaic energy conversion Ultraviolet photoemission spectroscopy

Electron Beam Evaporation was used to analyze the deposition of ultra-thin Barium Fluoride (BaF2) films on gallium arsenide wafers. Film thickness and chemical composition on the work function of the resulting heterostructure. X-ray photoemission spectroscopy combined with ultraviolet photoemission spectroscopy measurements reveals that films of 2 nm nominal thickness and Ba/F = 1.0 stoichiometry ratio induce the achievement of a significantly low work function of 2.1 eV to the BaFx/GaAs heterostructure. The significant reduction of the work function at least down to 3.0 eV is confirmed by a test thermionic converter operating at a cathode temperature of 1385 °C, where the heterostructure was applied as anode. The low work function, together with a negligible optical absorption, makes feasible the practical application of barium fluoride coatings on GaAs within hybrid thermionic-thermophotovoltaic devices.

Barium Fluoride Sputtering Targets

BaF2 thin films are sputtered on aluminum, silicon and glass solid substrates using electron beam evaporation (EBE) technique in vacuum (6 to 10 mbar) and at room temperature. The thickness of the barium fluoride deposited thin layer on the substrates mentioned above is nearly 20nm with a deposition rate of 0.4 to 0.5 nm per second. In the sputtering process, all substrates are precisely cleaned before depositing the BaF2. A quartz crystal is applied to monitor the thickness. After the deposition, the surface structure is characterized by Glancing Angle X-ray Diffraction (GAXRD) diffractometer. Atomic force microscopy is used to study the morphology of the thin film. According to the characterization data by XRD peaks, the crystallites size on silicon substrate appears to be remarkably smaller than aluminum and glass substrates. The thin film prepared in this way has numerous physical and chemical specifications so qualified enough to be applied in manufacturing high-tech microprocessors.

What is Barium Fluoride?

Inorganic compound with the formula BaF2, barium fluoride is found naturally in the rare mineral frankdicksonite. Under standard conditions, it takes on the structure of a fluorite. Under high pressure, it adopts that of PbCl2. Because it is resistant to water, it is insoluble in it. However, it is highly corrosive and is dangerous for humans.

Infrared BaF2 optical components have different shapes. Some are rods, while others are wedges or prisms. Some have cylindrical and spherical shapes. The shape of these optical components is very important for the efficiency of the device. They must be made from glass that is not contaminated by other substances.

Is a BaF2 Substrat Dissolved in Water a Safe Solution For Organic Solar Cells?

The first step to producing an organic solar cell is to dissolve the BaF2 substrate in acetone or IPA. Since the substrate can be used for both organic and inorganic solar cells, it is not a bad idea to add a few drops of IPA to the solution when manufacturing the cells. Nevertheless, this can be hazardous to the environment. This solution should be avoided when processing organic or inorganic solar cells.

For the process of electrolysis, the chemical reaction is performed using 2,4,7-tetramethyl-5-dekin-4-dioli (TMDDA). The IPA is used to remove tetramethylbenzene, a component of the BaF2 substrate. The IPA is a solvent and the acetone can be a solvent.

Using a surfactant is the first step to perform electrolysis. Typically, the catalyst is supported by a bimetallic material. IPA is commonly used in cloud chambers, where particles of radiation can condense the molecule and release the electrons. When dissolved in water, the resulting ion pairs will form a thin layer that enables the particle to condense.

In some cases, it is necessary to dilute the BaF2 substrate in acetone or IPA to reach the desired concentration. This may result in a chemical reaction that could lead to an unstable molecule. However, this solution can be useful for a variety of purposes. For example, the BaF2 substrate can be patterned by combining the materials with other materials.
