Abrupt NMOS Inverter Based on Punch-Through Impact Ionization With Hysteresis in the Voltage Transfer Characteristics

Mihai Adrian Ionescu, Didier Bouvet, Kirsten Emilie Moselund

In this letter, an abrupt NMOS inverter based on punch-through impact ionization is demonstrated for the first time. The slopes for both the rising and the falling edge of the ID(V GS) device characteristics are less than 10 mV/dec ...

Dye-sensitized solar cells with solvent-free ionic liquid electrolytes

Michael Graetzel, Shaik Mohammed Zakeeruddin, Peng Wang, Yu Bai, Yiming Cao

We systematically studied the temperature-dependent physicochemical properties, such as density, conductivity, and fluidity, of 1,3-dialkylimidazolium iodides. In combination with the amphiphilic Z907Na sensitizer, we have found that it is important to use ...

Fabrication and characterisation of polymer based solar cells

Thomas Söderström

Tandem solar cells, in which two individual cells are stacked on top of each other, offer the potential to increase the efficiency significantly compared to a single cell on the same area. To reach maximum efficiency, each cell in the stack must have a dis ...

Reversible, fast, and high-quality grid conversions

Dimitri Nestor Alice Van De Ville

A new grid conversion method is proposed to resample between two 2-D periodic lattices with the same sampling density. The main feature of our approach is the symmetric reversibility, which means that when using the same algorithm for the converse operatio ...

Origin of the large spectral shift in electroluminescence in a blue light emitting cationic iridium(III) complex

Mohammad Khaja Nazeeruddin

A new, but archetypal compound [ Ir( ppy- F-2) (2)Me(4)phen] PF6, where ppy- F2 is 2-(2',4'- fluorophenyl) pyridine and Me(4)phen is 3,4,7,8- tetramethyl- 1,10- phenanthroline, was synthesized and used to prepare a solid-state light-emitting electrochemica ...

Multi-objective thermoeconomic optimisation of the design of heliostat field of solar tower power plants

Solar thermal power is a very promising technique in the future, while the design of heliostat field, which decide the investment and the energy received, influences very much thermoeconomics of the power system so as the capital cost of the electricity ob ...

$ H _{ 2 } $ O: Reversible Hexagonal-Orthogonal Grid Conversion by 1-D Filtering

Dimitri Nestor Alice Van De Ville

In this work, we propose a new grid conversion algorithm between the hexagonal lattice and the orthogonal (a.k.a. Cartesian) lattice. The conversion process, named

H _{ 2 }

O, is easy to implement and is perfectly reversible using the same algorithm to ...

Efficiency Considerations and Measurements of a Hybrid Energy Storage System based on Compressed Air and Supercapacitors

Alfred Rufer

This paper presents the study and experimentation of a hybrid energy storage system based on Compressed Air, where the storage and discharge are done within maximum efficiency conditions for the volumetric machine. As these maximum efficiency conditions im ...
