Fabrication of 3D

1 This paper proposes the fabrication process of the first fully 3D-printed ceramic core structures for portable solar desalination devices optimized to tackle water scarcity from an energy and sustainability perspective. Robocasting, a 3D printing technique, is utilized to fabricate a fully ceramic structure of an integrated solar absorber/thermal insulator/water transporter based on the two

Effects of gas flow rate on the structure and elemental

As flow rate is increased to 30 sccm, it was found that i-SnO 2 films of the samples of S03 and S53 start to show some tendency of the films to form minor peaks indicating improved crystallinity. At 40 sccm flow rate, the i-SnO 2 film of the sample S54 showed slight improvement, while the films of the sample S04 showed significant improvement in XRD peaks.

Accurate Thermal Diffusivity Measurements Using a

To demonstrate the effectiveness of the custom instrument, the thermal diffusivity of a copper 110 foil (25.0 mm long, 7.0 mm wide, and 76.2 μm thick) was measured in ambient conditions, and the results match well with previous studies performed in vacuum

Thermal Oxidation

Thermal oxide (silicon dioxide) is a silicon dioxide film produced by the oxidation of substrate silicon, usually at temperatures in excess of 1000 C. Thermal oxides can be grown using a dry oxidation process: Si + O 2 → SiO 2 Or a wet oxidation process: Si + 2H 2 O → SiO 2 + 2H 2

Fabrication of Crystalline Silicon Solar Cell with Emitter

The thicknesses and refractive indices of the SiNx films prepared by PECVD under different gas flow ratios were characterized by Spectroscopic Ellipsometry. The parameters for the SiNx depositions were: chamber pressure 0.6 Torr, deposition temperature 300C, RF power density 0.08 W cm -2 at a 13.56 MHz frequency, silane (SiH 4 ) and ammonia (NH 3 ) source gases, deposition time 4 minutes

In this issue of Joule, Rolston and co-authors demonstrate rapid, air-ambient spray deposition of metal halide perovskite thin films at a rate of 12 m/min for efficient solar cell modules. Their findings point to the feasibility of scaling up perovskite photovoltaics at competitive costs, provided key issues with material instability can be solved.

Rapid thermal annealing of ITO films

2011/6/1Highlights ITO films were deposited at room temperature. ITO films were treated by rapid thermal annealing (RTA) in vacuum. ITO films after annealed by RTA shows the lowest resistivity of 1.6 10 −4 Ω cm. High transmittance (above 90%) is exhibited by the ITO films.

Improving carrier transport in Cu2O thin films by rapid

2018/1/24This study shows that post-deposition rapid thermal annealing (RTA) of Cu 2 O films is an effective approach for improving carrier transport in films prepared by reactive magnetron sputtering. The as-deposited Cu 2 O films were poly-crystalline, p -type, with weak near band edge (NBE) emission in photoluminescence spectra, a grain size of ~100 nm and a hole mobility of 2–18 cm 2 V −1 s −1 .

Chemical Vapor Deposition: Overview

Deposit conformal films without the need for high vacuum, onto substrates with irregular surfaces, or on large quantities of closely packed substrates. Chemical Vapor Deposition (CVD) is a process in which precursor gases react to form film deposits on a substrate.

Chemical Vapor Deposition

LPCVD uses the highest temperature to deposit films, typically above 600 C. The low-pressure environment creates a very uniform film with high purity, reproducibility, and homogeneity. This is performed between 10 – 1,000 Pa, while standard room pressure is 101,325 Pa. Temperature determines the thickness and purity of these films, with higher temperatures resulting in thicker and more pure


Avoiding the hazing of silicon nitride films requires some method of keeping the NH 4 Cl byproduct from back-streaming out of the vacuum manifold during loading and unloading. Tystar's innovative gate valve solves this problem by allowing a small continuous flow of nitrogen from the process tube to the pump when the gate valve is closed.

Fabrication of oxide layers

In thermal oxidation, silicon wafers are oxidized in furnaces at about 1000 C. The furnaces consist of a quartz tube in which the wafers are placed on a carrier made of quartz glass. For heating there are several heating zones and for chemical supply multiple pipes.

Nanoporous silk films with capillary action and size

Crystalline SF films (10 μm thick) were obtained after drying and vacuum annealing at room temperature of aqueous SF solutions under the experimental conditions detailed in ref. 12. The crystallization protocol was completely green and water-based, and allowed the incorporation of water-soluble biomolecules in the SF matrix, e.g. enzymes, while preserving their structure and function.
