Increasing analyzable steel thickness for thin layer activation experiments
Nuclear Science and Techniques, 2020The thin layer activation technique (TLA) is very effective in wear analysis for tribological systems where disassembly is costly or impractical. Since its development in the 1970s, TLA has been applied through direct irradiation of solid targets using ionizing particle beams to obtain an activation with a specific profile. This profile is then used to

Decreasing the thickness of the active layer of microcrystalline silicon TFTs
physica status solidi c, 2010AbstractTop‐gate TFTs are fabricated at T < 200 °C using μc‐Si:H film with different thickness, 30, 100 and 200 nm as active layer. Silicon nitride deposited at 150 °C is used as gate insulator. Due to improved crystallinity, mobility increases with the μc‐Si:H thickness.

Thick
Comprehensive SummaryOrganic solar cells (OSCs) present a promising renewable energy technology due to their cost‐effectiveness, adaptability, and lightweight nature. The advent of non‐fullerene acceptors has further boosted their significance, allowing for power conversion efficiencies surpassing 19% even with an active layer thickness of about 100 nm.

Ternary thick active layer for efficient organic solar cells
Journal of Materials Science, 2018Ternary organic solar cells (OSCs) hold great promise in enabling the roll-to-roll printing of environmentally friendly, mechanically flexible, and cost-effective photovoltaic devices. Nevertheless, many ternary OSCs display the best power conversion efficiency (PCE) with a thin active layer at the thickness of about 100 nm, which can be hardly ...

Active layer thickness calculation over the Qinghai–Tibet Plateau
Cold Regions Science and Technology, 2009Abstract The rising air temperature and increased human activities have caused permafrost degradation over the Qinghai–Tibet Plateau, including thickening of the active layer. The active layer plays an important role in cold regions. Active layer thickness (hereafter ALT) variation may have profound socio-economic and eco-environmental consequences ...

Active Layer Thickness Prediction on the Western Antarctic Peninsula
Permafrost and Periglacial Processes, 2015AbstractThe effects of climate change along the climatically sensitive Western Antarctic Peninsula (WAP) on active layer dynamics have just begun to be monitored. But extreme climates and difficult access make borehole installation here challenging. This study was designed to examine the ability of two commonly used, minimally intrusive techniques (the

Exciton polaritons in ZnO microcavities with different active layer thicknesses
physica status solidi (b), 2010AbstractWe have investigated the characteristics of exciton polaritons in ZnO microcavities with different active layer thicknesses. The microcavity was made from a bulk ZnO active layer and two distributed Bragg reflectors (DBRs) consisting of HfO2 and SiO2 layers.

Active Layer Thickness Measurement System For Double Heterostructure Laser Wafers
Optical Engineering, 1989A novel noncontact, nondestructive method for measuring the active layer thickness of InP/InGaAsP double heterostructure laser materials has been developed. This method is principally based on the evaluation of the net absorption through the active layer by measuring the transmission light power.

Optimization of SnS active layer thickness for solar cell application
Journal of Semiconductors, 2017This work presents a comparative study of n-SnS and p-SnS active layers for increased solar cell efficiency. Tin sulphide thin films of various thicknesses having p-type and n-type conductivity were fabricated by thermal evaporation. Both type of films had the same (113) orientation of the crystal planes with a constant tensile strain of ~ 0.003 and ...

The thickness of active layer dependence of polymer solar cells
10th IEEE International Conference on Nanotechnology, 2010We studied the active layer thickness dependence of device performance of bulk heterojunction solar cells. The polymer solar cells comprising RR-P3HT:PCBM (1∶0.8 (wt %:wt%)) blend films with different thickness (from 80 nm to 340 nm) were characterized.
