Using this process, the uniformity of large area thin layer can be retained, and the applicability to various substrates can provide great opportunities in the fabrication of various atomically thin layered structures.
Oxygen gas is added during the field emission process, and the uniformity of both emission area and brightness of a CNT pixel array are dramatically improved by 83%and90%0%, respectively, without reducing emission stability.
The prototype was tested at the Fermilab Test Beam Facility in October 2013 and the analysis of the test beam data demonstrates an excellent response uniformity of the large area chamber with an efficiency higher than 95%.
Accordingly, less than 2% spread in uniformity of the large-area ion beam is achieved.
The measurement result of the spatial radiance uniformity of the large-area ISURS was 99.19%.
The final divergence angle is 5.997 mrad, close to the theoretical calculation value 1.92 mrad, and the illumination uniformity of the predetermined illumination area on the receiver is better than 93.02%.
Area powder XRD studies demonstrated reasonable uniformity of CC3 distribution across the area of the membrane.
By also performing the analysis based on the uniformity of strut cross-sectional areas, it is shown that the non-uniformity of cross-sectional areas is an important factor for the buckling behavior of open-cell foams.
Beyond the apparent uniformity of the landscapes in areas characterized by intensive agriculture, the results highlight the diversity of the local populations and confirm the heuristic significance of the notion of community of relationships to the landscape.
Sol-gel technique, a most used and mature way to synthesize various function materials under the right conditions, has been widely used in scientific researches and technical exploitations and has a distinct advantage over other methods in the uniformity of film thickness, large-area fabrications, precise controls of chemical composition, etc. compared with pulsed laser deposition (PLD) [13, 14].
