2022 MRS Fall Meeting & Exhibit

Symposium EQ07-Diamond Electronics, Devices and Sensors—From Synthesis to Applications

Due to its unique properties diamond is a material that enables applications in challenging environments. Recent development in the areas of RF and power electronics, heat spreaders, sensors, MEMs, room temperature quantum applications, tissue engineering and catalysis at extreme potentials are among the most promising. This was fueled by achievements such as significant improvements in single crystalline diamond homo- and hetero-epitaxial growths 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. Selective doping techniques enable the development of high quality electronic components made out of diamond such as vertical and lateral devices, Schottky junctions, pin-diodes and field-effect-transistors. In addition, diamond based electron emitters for the generation of solvated electrons in buffer solutions are currently being developed to reduce CO(2) or N(2) into fuels, chemical building blocks or ammonia, as a means to cope with greenhouse gas emissions and the increasing demand for fuels and fertilizers. Further, the application of lattice defects such as NV, GeV and SnV 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 diamonds 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 as biomarkers and for drug delivery, cancer diagnosis and therapy as well as in tissue engineering and catalysis. Diamond coatings have demonstrated they can be biocompatible and can be functionalized for in-vivo applications ranging from tissue engineering to neuron interfaces and stimulants. This symposium will bring together researchers from academia and industry, to discuss and introduce the perspectives and possibilities of diamond as well as diamond hybrid materials and heterojunction development. As recurring since 2006, this symposium promotes new applications, new ideas and collaborations in the science communities ranging from biology, quantum technology to electronic applications all over the world. Joint sessions on diamond growth and doping for quantum applications can be organized in collaboration with other symposia as established in previous editions.

  • Advances in large area homo- and hetero-epitaxial-growth of single-crystalline diamond
