In the simulation, the OLED was divided into 1 µm × 1 µm sections andPOLEDwas normalized to a value of 1. The OLED emission pattern was calculated using the same simulation as the outcoupling efficiency. We simulated the emission pattern of the PNPN-OLED emitting to parylene...
However, tolerances in the thicknesses of the multiple layers that compose the VM-PVLPC, including the semiconductor structure and the ARC, produce much more important conversion efficiency losses than in typical multijunction solar cells. Similarly, as with the effect of detuning of the laser ...
, recent studies suggest that optimising laser processing parameters can yield a uniform layer of η-Fe2Al5 IMCs at the interface between Fe- and Al- rich regions, free from problems like hot and cold cracks, ultimately contributing to improved strengths of up to 4 kN (105.3 N/mm2)11...
The Ce:Nd:YAG solar laser presented only 0.35 W/mm3 maximum heat load, 307.9 K maximum temperature, and 10.8 N/mm2 maximum thermal stress values, which are substantially lower than that of most recent Fresnel lens single Ce:Nd:YAG solar laser pumping scheme [22], ensuring consequently ...

where ‘Cp’ is the capacitance across the sample (μF), ‘d’ is the thickness of grown crystal (mm), ‘A’ is the cross-sectional area of the sample (mm2), ‘εo’ is the free space permittivity (8.854 × 10−12F m−1), and ‘tanδ’ is the dissipation factor. The dielec...
When the biofilms on the carriers from sites 26 mb, 26 db, and 36 mb were analysed, in terms of the number of cells of six distinct morphotypes present on the 6 mm2 surface area [Figure 4], it was obvious that the colonisation was very luxuriant and that the three sulci differed very...
to produce eight pieces of deuterated foil with a size of ~ 25 × 50 mm2 each (Fig. 6a). Once the films are prepared, the first important question that arises is about their thickness. The rough but simple estimation of the thickness was based on the measurement of the surface and ...
Fracture strength 180-210 N/mm2 Fig. 4 illustrates the four-level energy diagram of Nd: YAG laser material. The solid-state Nd: YAG laser is a four-level system except at the wavelength of 946 nm. The advantage of a four-level laser system is that the population inversion is attained ...
where q is laser energy density, the unit is J/mm2, W is laser power, H is laser spot diameter, and v is scanning speed. Laser energy density plays a decisive role in SLS forming, and its size is related to laser power, scanning speed, and scanning spacing [27]. To obtain the sui...
