Scaling Design Effects on Surface Buffer IGBT Characteristics

IEEE Journal of the Electron Devices Society, 2022
Scaling design effects on surface buffer (SB) insulated gate bipolar transistor (IGBT) is analyzed not only for power loss reduction but also for switching controllability and robustness using TCAD simulation.

Could the negative capacitance effect be used in field-effect transistors with a ferroelectric gate?

Фізика і хімія твердого тіла, 2022
We analyze the electric potential and field, polarization and charge, and differential capacitance of a silicon metal-oxide-ferroelectric field effect transistor (MOSFET), in which a gate insulator consists of thin layers of dielectric SiO2 and weak ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Effect of interfacial conductivity on electrical characteristics of negative capacitance field effect transistors

Materials Research Express, 2021
In this article, an interfacial conductivity model for the surface potential and the drain current was proposed based on the metal-interface-ferroelectric-insulator-semiconductor (MIFIS) structure negative capacitance field effect transistor (NC-FET ...

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Adaptive piezoelectric shunt damping by self-tuning negative capacitor

Nihon Kikai Gakkai ronbunshu, 2014
A self-tuning negative capacitor is proposed for a piezoelectric shunt damping system; unknown capacitance of the piezoelectric element is estimated by an online estimator without introducing additional sensors and the negative capacitor is tuned based ...

Elastic Amplification from Negative Capacitance

Physical Review Letters
Ferroelectrics under suitable electric boundary conditions can present a negative capacitance response, whereby the total voltage drop across the ferroelectric opposes the externally applied bias. When the ferroelectric is in a heterostructure, this behavior yields a voltage amplification in the other elements, an effect that could be leveraged in low ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Epigenetic heterogeneity and plasticity in therapy‐induced tumor states through single‐cell multi‐omics

Molecular Oncology, EarlyView.
Single‐cell multi‐omics reveals epigenetic heterogeneity across therapy‐adaptive tumor states, including quiescent/dormant, drug‐tolerant persister, and EMT‐like phenotypes. By linking regulatory features with state‐associated biomarkers, these approaches inform biomarker‐guided therapeutic strategies for evolving tumors.
