The Role of Ultra‐Thin Buffer Layers for Achieving Ultra‐Low Dark Currents in Single‐Component Organic Photodetectors

open access: yesAdvanced Functional Materials, EarlyView.
Here, SubNc single‐component organic photodiodes (SC‐OPDs) are investigated, which achieve highly competitive performance metrics, including high EQE, ultra‐low JD, and high specific detectivity (D*). This study emphasizes the critical role of an organic buffer layer in studying the interface energetics and effects to achieve state‐of‐the‐art ...

Minimizing noise-temperature measurement errors [PDF]

open access: yes
An analysis of noise-temperature measurement errors of low-noise amplifiers was performed. Results of this analysis can be used to optimize measurement schemes for minimum errors. For the cases evaluated, the effective noise temperature (Te) of a Ka-band

Atomic Layer Deposition in Transistors and Monolithic 3D Integration

open access: yesAdvanced Functional Materials, EarlyView.
Transistors are fundamental building blocks of modern electronics. This review summarizes recent progress in atomic layer deposition (ALD) for the synthesis of two‐dimensional (2D) metal oxides and transition‐metal dichalcogenides (TMDCs), with particular emphasis on their enabling role in monolithic three‐dimensional (M3D) integration for next ...

Sensitized Triplet Exciton Generation in Nanostructured Polymer Scintillators: Toward Improved γ/Neutron Discrimination

open access: yesAdvanced Functional Materials, EarlyView.
Rapid γ/neutron discrimination through PSD is achieved in liquid droplet containing nanostructured polymeric scintillator where a TTA‐active dye is dissolved. The inclusion of a properly selected and dosed sensitizer metalated porphyrin enhances discrimination sensitivity and speed by doubling the density of annihilating triplets and increasing the ...

Cross-sectional Analysis of Sound Levels in the Neonatal Intensive Care Unit (NICU) at Thomas Jefferson University Hospital [PDF]

open access: yes, 2019
Introduction . Infants in the NICU are considered at greater risk of developmental delay. It is now known that excessively loud noise can have a negative impact on parameters such as blood pressure, breathing, heart beat and oxygen saturation.

Use of noise correlation matrices to interpret ocean ambient noise

open access: yesThe Journal of the Acoustical Society of America, 2019
Oceanic ambient noise is a dynamic mixture of biologic, geophysical, and anthropogenic sound sources. A goal of research is to put some order in this cacophony of information, understand the received spectral content and determine the primary contributors to the ambient noise.
