Symposium F.EL01-Diamond and Diamond Heterojunctions—From Growth to Applications

The properties of diamond are promising for extreme and new applications in technology like high power laser lenses, head spreaders in power LEDs, room temperature quantum applications, power electronics and bipolar high-frequencies devices to name a few. Significant improvements in single crystalline diamond homo- and hetero-epitaxial growths have been achieved over recent years due to the increased demand for high quality single crystalline diamond films with large and smooth surfaces (opto-electronics, waveguides), defect free surfaces, which can be wafer bonded to III-V-materials and 3D-device -architectures for power electronics.

In the field of diamond electronics, recent breakthroughs in selective doping techniques have been demonstrated and applied for the development of high quality diamond-based electronic components ranging from vertical to lateral devices, from Schottky junctions, pin-diodes to field-effect-transistors. In addition, diamond based electron emitters for the generation of solvated electrons in buffer solutions are currently being developed to reduce CO2 or N2 molecules, intending to revolutionize the Haber-Bosch process in the future. In addition, the application of nitrogen-vacancies centers for magnetometry gains increasing momentum for the generation of new devices related to navigation, local current sensing, geology, MRI and many more. Hybrid electronic systems that combine diamond’s excellent thermal properties with materials such as GaN based MMICs have been demonstrated, where diamond is applied on the back side by wafer bonding but also on the hot-spot gate (front side) by plasma deposition. Beyond monocrystalline diamond, applications of functionalized nanodiamonds have emerged as biomarkers and for drug delivery, cancer diagnosis and therapy. Diamond coatings are biocompatible and can be functionalized for in-vivo applications ranging from neuron interfaces to brain surgeries and stimulants.

This symposium will bring together researchers from academia and industry, to discuss and introduce the manifold possibilities of diamond and diamond hetero-junctions to stimulate new applications, new ideas and collaborations in the science communities ranging from biology, quantum-tech to electronic applications in US, Europe and Asia.

Topics will include:

Advances in homo- and hetero-epitaxial-growth of single-crystalline diamond.
Novel bonding approaches to manufacture diamond to III/V and other materials
Diamond optical applications in high power laser systems.
Defects, impurities and doping of diamond and correlated electrical, optical and mechanical properties.
Diamond for magnetometry and single photon-generation, including fundamental properties of color centers (NV, SiV, GeV, etc), new quantum devices and applications (supporting architectures, wave-guides, couplers, etc).
