Diamond Window Technology for Electron Cyclotron Heating and Current Drive: State of the Art

Nuclear fusion power plants require electron cyclotron (EC) heating and current drive (H&CD) systems for plasma heating and stabilization. High-power microwave beams between 1 and 2?MW generated by gyrotrons propagate in a dedicated waveguide transmission ...

Towards a coherent database of thermal boundary conductance at metal/dielectric interfaces

Ludger Weber, Maïté Blank

The thermal boundary conductance (TBC) of metal/dielectric couples was measured for a large variety of metals on silicon, sapphire, and diamond using time domain thermoreflectance and compared to data previously obtained on diamond. In the case of silicon, ...

High-quality single crystal diamond diffraction gratings fabricated by crystallographic etching

Olivier Martin, Toralf Scharf, Niels Quack, Christian Santschi, Teodoro Graziosi, Marcell Kristof Kiss, Adrien Marc Toros

We demonstrate a novel method for fabricating single crystal diamond diffraction gratings based on crystallographic etching that yields high-quality diffraction gratings from commercially available diamond plates. Both V-groove and rectangular gratin ...

Advanced Diamond Microfabrication for Microoptics and Photonics

Marcell Kristof Kiss

Diamond is an exceptional material - hard, stiff, transparent, which makes it ideal for the fabrication of optical and mechanical systems that take advantage of these properties. Diamond is not only "better", but it offers the possibility of integrating br ...

Fabrication and Characterization of Freestanding Single Crystal Diamond and Silicon Microresonators

Teodoro Graziosi

Microresonators are fundamental building blocks of any photonic integrated circuit, as they can be used as filters, modulators, sensors, and to enhance light emission. If these resonators are suspended and are free to oscillate, we can exploit the interact ...

Chemo-mechanical effects on the tribocorrosion behavior of titanium/ceramic dental implant pairs in artificial saliva

Anna Neus Igual Muñoz, Alejandro Roda Buch

In this paper, the degradation mechanisms of the ceramic and the metal in Titanium/Zirconia pairs for biomedical applications were analyzed. To do that, an experimental set-up with well-controlled mechanical and chemical conditions was used based on a unid ...

H-terminated polycrystalline diamond p-channel transistors on GaN-on-Silicon

Elison de Nazareth Matioli, Remco Franciscus Peter van Erp, Reza Soleiman Zadeh Ardebili, Riyaz Mohammed Abdul Khadar, Mehdi Naamoun

In many semiconductor technologies, including GaN, the lack of p-channel devices is a major obstacle for complementary operations. Here, we demonstrate high-performance polycrystalline diamond p-channel transistors on GaN-on-Si. Following the optimization ...

Heat-transfer at the interface between a metal and a non-metal: influence of ultra-thin interlayers, interface chemistry and atomic order

Maïté Blank

The Thermal Boundary Conductance (TBC) at the interface between metals and dielectrics is of key importance for heat transport in structures heterogeneous on a scale from 100 µm downwards. In this thesis the TBC of a large number of metal/dielectric couple ...

Broadened Bandwidth Amplified Spontaneous Emission from Blue GaN-Based Short-Cavity Superluminescent Light-Emitting Diodes

Hua Zhang, Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Denis Martin, Hezhi Zhang

We report broad bandwidth blue superluminescent light-emitting diodes (SLEDs) based on a short-cavity active region. The dependencies of amplified spontaneous emission (ASE) output power and gain bandwidth on cavity length were investigated in devices whos ...

Growth kinetics and morphological analysis of homoepitaxial GaAs fins by theory and experiment

Anna Fontcuberta i Morral, Gözde Tütüncüoglu, Martin George Friedl, Lea Ghisalberti

Nanoscale membranes have emerged as a new class of vertical nanostructures that enable the integration of horizontal networks of III-V nanowires on a chip. To generalize this method to the whole family of III-Vs, progress in the understanding of the membra ...
