1. An Amorphous Silicon Photo TFT with Si3N4/Al2O3 or HfO2 Double Layered Insulator for Digital Imaging Applications
Abstract This paper focuses on amorphous silicon photo thin-film transistors with double layered insulator using Si3N4/Al2O3 or HfO2 as candidates for the succession of Si3N4 as a traditional insulator in the fabrication of hydrogenated amorphous silicon thin-film transistors. Whether for industry or for research, there is a need to investigate the use of th

4. Andreev transport in double quantum dots coupled to superconductor and ferromagnetic leads / Transporte por reflexão de Andreev em pontos quanticos duplos acoplados a eletrodos supercondutores e ferromagneticos
In this work we studied the quantum transport in two hybrid nanostructures composed of double quantum dots (DQD)s coupled to superconductor (S) and ferromagnetic (F) leads. The first nanostructure, denoted by F - QDa - QDb - S, is composed of a ferromagnet, two quantum dots, and a superconductor connected in series. In the second nanostructure, denoted by (

5. Magnetotransporte em poços-quânticos de AlGaAs/GaAs com diferentes formas de potencial / Magnetotransport in AlGzAs/GzAs quantum wells with different potential shapes
In this thesis we present studies of magnetotransport in double quantum wells (DQWs) in low magnetic fields and under application of an external electric field (gate potential). Measurements of magnetoresistance have been carried out in both linear and non-linear regime. We report on the observation of magneto-intersubband (MIS) oscillations for the first ti

7. Theoretical-experimental study of the drain current transient and generation lifetime in SOI MOSFETs technologies. / Estudo teórico-experimental do transitório da corrente de dreno e do tempo de vida de geração em tecnologias SOI MOSFETs.
This work presents a study of drain current switch-off transients and extraction methods of the generation lifetime in partially depleted SOI nMOSFET transistors of single gate, double gate and triple gate FinFETs. This study is accomplished through two-dimensional numerical simulations and compared with experimental data of devices fabricated in the IMEC (I

8. Conductance through two quantum dots in a ring: magnetic flux dependence
The conductance of a double-dot system in a ring threaded by a magnetic flux is studied. The ring is connected to two leads in such a way that each dot is embedded in one arm of the structure. The currents going through each arm of the ring are determined by the Aharonov-Bohm effect and the dot charging effects. The conductance for different values of the ma

9. Hook-length control of the export-switching machinery involves a double-locked gate in Salmonella typhimurium flagellar morphogenesis.
During flagellar morphogenesis in Salmonella typhimurium, the genes involved in filament assembly are expressed fully only after completion of hook-basal body assembly. This coupling of gene expression to morphogenesis is achieved by exporting the flagellum-specific anti-sigma factor, FlgM, out of the cell through the mature hook-basal body structure. Theref

10. A model for the mechanism of strand passage by DNA gyrase
The mechanism of type II DNA topoisomerases involves the formation of an enzyme-operated gate in one double-stranded DNA segment and the passage of another segment through this gate. DNA gyrase is the only type II topoisomerase able to introduce negative supercoils into DNA, a feature that requires the enzyme to dictate the directionality of strand passage.

11. A Double Tyrosine Motif in the Cardiac Sodium Channel Domain III-IV Linker Couples Calcium-dependent Calmodulin Binding to Inactivation Gating
Voltage-gated sodium channels maintain the electrical cadence and stability of neurons and muscle cells by selectively controlling the transmembrane passage of their namesake ion. The degree to which these channels contribute to cellular excitability can be managed therapeutically or fine-tuned by endogenous ligands. Intracellular calcium, for instance, modu

12. Helicase-appended Topoisomerases: New Insight into the Mechanism of Directional Strand Transfer*
DNA strand passage through an enzyme-mediated gate is a key step in the catalytic cycle of topoisomerases to produce topological transformations in DNA. In most of the reactions catalyzed by topoisomerases, strand passage is not directional; thus, the enzyme simply provides a transient DNA gate through which DNA transport is allowed and thereby resolves the
