Base Station Performance Model

, 2005
At present the testing of power amplifiers within base station transmitters is limited to testing at component level as opposed to testing at the system level. While the detection of catastrophic failure is possible, that of performance degradation is not. This paper proposes a base station model with respect to transmitter output power with the aim of

Highly‐Emissive Organic Photovoltaics Approaching Theoretical Limit Voltage and Enabling Multifunctional Energy‐Harvesting Displays

Advanced Materials, EarlyView.
A highly‐emissive organic photovoltaic employs donor–acceptor pairs with alternately localized frontier molecular orbitals, preserving high triplet energies and small reorganization energies to suppress non‐radiative recombination. As a result, it exhibits a high open‐circuit voltage approaching the Shockley–Queisser limit and a high ...

A Scalable Perovskite Platform With Multi‐State Photoresponsivity for In‐Sensor Saliency Detection

Advanced Materials, EarlyView.
A scalable in‐sensor computing platform (32 × 32 array) with ultra‐low variability is developed by incorporating ferroelectric copolymers into halide perovskite thin films. These devices achieve 1000 programmable photoresponsivity states and high thermal reliability.

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Impact of Oxygen Plasma Pre‐Treatment on Thermal Oxidation and Reliability of SiO2 on 4H‐SiC

Advanced Materials Interfaces, EarlyView.
We investigate how oxygen plasma pre‐treatment affects the thermal oxidation of silicon carbide. While plasma modification increases growth rates by 84%, it reduces dielectric breakdown strength by 18%. Our findings reveal that although plasma improves the interface state density, it introduces structural damage, highlighting a critical trade‐off ...
