Tensile strain regulation via grain boundary buffering for flexible perovskite solar cells

Nature Communications
Flexible perovskite solar cells show promise in photovoltaics due to their high energy-to-power efficiency and adaptability, making them a top choice for third-generation thin-film solar applications. However, the inherent defect and mechanical fragility

Tunable pulse delay and advancement in a coupled nanomechanical resonator-superconducting microwave cavity system

, 2010
We theoretically study the transmission of a weak probe field under the influence of a strong pump field in a coupled nanomechanical resonator-superconducting microwave cavity system. Using the standard input-output theory, we find that both pulse delay (

Noise properties of two single electron transistors coupled by a nanomechanical resonator

, 2005
We analyze the noise properties of two single electron transistors (SETs) coupled via a shared voltage gate consisting of a nanomechanical resonator. Working in the regime where the resonator can be treated as a classical system, we find that the SETs ...

LOCAL NANO-MECHANICAL PROPERTIES OF CROSS-LINKED POLYBUTYLENE

Acta Polytechnica CTU Proceedings, 2020
Cross-linking is a process in which polymer chains are associated through chemical bonds. The cross-linking level can be adjusted by the irradiation dosage and often by means of a cross-linking booster. The polymer additional cross-linking influences the
