Subsurface fluorescence time-of-flight imaging using a large-format single-photon avalanche diode sensor for tumor depth assessment
Edoardo Charbon, Claudio Bruschini, Arin Can Ülkü, Yichen Feng
Significance: Fluorescence guidance is used clinically by surgeons to visualize anatomical and/or physiological phenomena in the surgical field that are difficult or impossible to detect by the naked eye. Such phenomena include tissue perfusion or molecula ...
Spie-Soc Photo-Optical Instrumentation Engineers2024Shining Diamond: from Micro- and Nano-Engineering to Quantum Photonics
The discovery of room-temperature single photon emission from color centers in diamond has in recent years boosted research interest in this renowned material in photonics and quantum community and beyond. Following understanding some basic principles of h ...
EPFL2021Diamond diffractive optics-recent progress and perspectives
Niels Quack, Gergely Huszka, Sichen Mi
Diamond is an exceptional material that has recently seen a remarkable increase in interest in academic research and engineering since high-quality substrates became commercially available and affordable. Exploiting the high refractive index, hardness, las ...
WALTER DE GRUYTER GMBH2021Exploring optically active defects in wide-bandgap materials using fluorescence microscopy
Defects in solid-state systems can be both detrimental, deteriorating the quality of materials, or desired, thanks to the novel functionality they bring. Optically active point defects, producing fluorescent light, are a great example of the latter. Natura ...
EPFL2021Single crystal diamond gain mirrors for high performance vertical external cavity surface emitting lasers
Niels Quack, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Pascal Gallo, Gergely Huszka, Mehdi Naamoun
We report on the design, fabrication and optical performance of gain mirrors in single crystal diamond substrates for vertical external cavity surface emitting lasers (VECSELs). VECSELs have gained attention recently due to their potential for high emissio ...
2020Transition metal clusters on h-BN/Rh(111)
The main aim of this dissertation is to study the catalytic aspects of very small transition metal clusters supported on h-BN/Rh(111). The catalytic reactions of interest were ammonia synthesis and CO oxidation on mass selected and soft landed iron and pla ...
EPFL2017A robust molecular probe for Ångstrom-scale analytics in liquids
Andras Kis, Dumitru Dumcenco, Heike Riel, Christos Dimitrakopoulos
Traditionally, nanomaterial profiling using a single-molecule-terminated scanning probe is performed at the vacuum-solid interface often at a few Kelvin, but is not a notion immediately associated with liquid-solid interface at room temperature. Here, usin ...
Nature Publishing Group2016Unique large diamonds in a ureilite from Almahata Sitta 2008 TC3 asteroid
The Almahata Sitta MS-170 ureilite (a piece of a breccia originating from the asteroid, 2008 TC3) consists mainly of olivine, with many diamond and graphite grains existing between the olivine grains. The occurrences of the diamonds are unique; i.e., (i) s ...
Pergamon-Elsevier Science Ltd2015Surface Kinetics of Titanium Isopropoxide in High Vacuum Chemical Vapor Deposition
Patrik Willi Hoffmann, Yury Kuzminykh, Michael Oliver Reinke
Understanding the surface kinetics of precursor decomposition during thin film formation represents a key aspect in the understanding and engineering of chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes. The determination of activ ...
American Chemical Society2015Influence of a Nanometric Al2O3 Interlayer on the Thermal Conductance of an Al/(Si, Diamond) Interface
Christian Monachon, Ludger Weber
The effect of an Al2O3 interlayer on the thermal conductance of metal (Al)/non-metal (diamond and silicon) interfaces is investigated using Time Domain ThermoReflectance (TDTR). Interlayers between 1.7 and 20nm are deposited on oxygen-terminated diamond an ...
