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 ...

Balancing Electrons to Break the Activity‐Selectivity Trade‐Off in H2O2 Electrosynthesis

open access: yesAdvanced Functional Materials, EarlyView.
Carrier‐concentration balancing in CuS is achieved by coupling cobalt dopants with cobalt vacancies, converting CuS from p‐ to n‐type to accelerate 2e− ORR while withdrawing excess carriers to optimize *OOH binding for H2O2 desorption. The catalyst reaches 8.14 mol g−1 h−1 with >84% selectivity in 1.0 M KOH and drives robust electro‐Fenton dye ...

3D‐Printed Hygroscopic Polymer Networks for High‐Humidity Triboelectric Nanogenerators to Wirelessly Power Implantable Electronic Devices‐ A Conceptual Pathway

open access: yesAdvanced Functional Materials, EarlyView.
This work develops 3D‐printable tribopolymer networks that can enhance triboelectric performance under high humidity environments. Polar hydrophilic functional groups and incorporation of zwitterionic monomers promote bound‐water–dominated interfacial polarization thereby increasing electrical outputs.

Fast Track to the Overdoped Regime of Superconducting YBa2Cu3O7‐δ Thin Films via Electrochemical Oxidation

open access: yesAdvanced Functional Materials, EarlyView.
Overdoping high temperature superconductors, such as YBa2Cu3O7‐δ (YBCO), is expected to maxime the critical current density by optimising the condensation energy for a given defect landscape, providing new thrust for the development of fusion enabling coated conductors. Here, precise oxygen control is achieved via an electrochemical method allowing for

Microlensing path parametrization for Earth-like Exoplanet detection around solar mass stars

open access: yes, 2018
We propose a new parametrization of the impact parameter u0 and impact angle {\alpha} for microlensing systems composed by an Earth-like Exoplanet around a Solar mass Star at 1 AU.
