Integrated photonic devices in single crystal diamond

Niels Quack, Teodoro Graziosi, Sichen Mi, Marcell Kristof Kiss

The field of diamond photonics is reviewed, with a focus on recent experimental demonstrations of photonic integrated devices in a single crystal diamond. This field leverages the outstanding material properties of diamond with the aim to establish large-s ...

Facet-driven formation of axial and radial In(Ga)As clusters in GaAs nanowires

Anna Fontcuberta i Morral, Lucas Güniat, Santhanu Panikar Ramanandan, Didem Dede, Martin George Friedl, Jean-Baptiste Leran, Wonjong Kim, Nicolas Tappy, Akshay Balgarkashi

Embedding quantum dots in nanowires (NWs) constitutes one promising building block for quantum photonic technologies. Earlier attempts to grow InAs quantum dots on GaAs nanowires were based on the Stranski-Krastanov growth mechanism. Here, we propose a nov ...

Non-contact polishing of single crystal diamond by ion beam etching

Niels Quack, Teodoro Graziosi, Sichen Mi

We propose a non-contact surface finishing method for brittle substrates by ion beam etching and we experimentally demonstrate polishing of (100) single crystal diamond surface. We model and simulate the polishing process, and verify the results experiment ...

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, Niels Quack, Christian Santschi, Toralf Scharf, Teodoro Graziosi, Marcell Kristof Kiss

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 ...

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

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

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 ...

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 ...

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 ...

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 ...
