Heavily boron-doped diamond grown on scalable heteroepitaxial quasi-substrates: A promising single crystal material for electrochemical sensing applications

In this work, three distinct heteroepitaxial single-crystal boron-doped diamond (SC-BDD) electrodes were fabricated and subjected to detailed surface analysis and electrochemical characterization. Specifically, the heteroepitaxy approach allowed to synthesize large-area (1 cm²) and heavily-doped (100)-oriented SC-BDD electrodes....

Role of sp² carbon in non-enzymatic electrochemical sensing of glucose using boron-doped diamond electrodes

Boron-doped diamond (BDD) is of increasing interest for applications in electrochemical sensing. It is well known that the sp² carbon content in BDD influences its electrochemical properties as electrode material. In this work, evidence is provided that the surface sp² carbon content plays a crucial role in the...

Inkjet-printed high-Q nanocrystalline diamond resonators

Diamond is a highly desirable material for state-of-the-art micro-electromechanical (MEMS) devices, radio-frequency filters and mass sensors, due to its extreme properties and robustness. However, the fabrication/integration of diamond structures into Si-based components remain costly and complex. In this work, a lithography-free, low-cost...

Template-assisted bottom-up growth of nanocrystalline diamond micropillar arrays

Micro-patterned diamond has been investigated for numerous applications, such as biomimetic surfaces, electrodes for cell stimulation and energy storage, photonic structures, imprint lithography, and others. Controlled patterning of diamond substrates and moulds typically requires lithography-based top-down processing, which is costly and...

Laser-induced Periodic Surface Structures (LIPSS) on heavily boron-doped diamond for electrode applications

Diamond is known as a promising electrode material in the fields of cell stimulation, energy storage (e.g., supercapacitors), (bio)sensing, catalysis, etc. However, engineering its surface and electrochemical properties often requires costly and complex procedures with addition of foreign material (e.g., carbon nanotube or polymer) scaffolds...
