Challenges and Opportunities
Diamond holds immense promise for transforming quantum electronics, boasting an ultra-wide band gap of 5.47 eV and unparalleled properties compared to other wideband gap materials like Gallium Nitride or Silicon Carbide. Diamond, with its ultra-high band gap, exceptionally high thermal conductivity, low on-state resistance, and high breakdown voltage, is positioned as the material of choice for high-voltage, high-power, high-temperature, and high-frequency devices in critical semiconductor applications. Its unique band structure facilitates easy electron emission to vacuum levels at elevated voltages, potentially leading to high-hole conduction, making it suitable for diodes, transistors, and metal-oxide-semiconductor field-effect transistors. However, challenges related to doping and defect density reduction persist, hindering the realization of its full potential in electronics development. Addressing these challenges could unlock significant opportunities for diamond-based technologies, including enhanced thermal management and system compaction, ultimately driving innovation in the semiconductor industry.
Defect Challenges in Diamond Doping
At Diamond Quanta, we aim to overcome the challenges associated with successfully doping diamond and the presently limiting defectivity and charge transport issues associated with the traditional approach.
Doping Mechanisms and Defects
The progress of electronic devices utilizing diamond has been hampered by the complex mechanisms involved in diamond doping. Diamond defects, whether intrinsic or extrinsic, pose significant challenges. Dislocations, prevalent in various forms of diamond, including microcrystalline and nanocrystalline types, adversely impact electronic performance by introducing volume strain, altering electronic states within the band gap, and affecting surface morphology. Despite efforts to minimize defects through ultrapure diamond growth, the introduction of doping reintroduces deleterious effects.
Implications of N-Type Doping
N-type doping in diamond induces geometric distortions, reducing diamond volume energy by eliminating degenerate electronic states. These distortions significantly impact electronic states and, consequently, transport properties. Carriers in an electric field utilize localized trap states associated with vacancies or defects, a mechanism known as trap-assisted hopping or variable range hopping. The low mobility of carriers due to strong localization and increased scattering from irregular potential landscapes created by defects results in reduced carrier velocity and mobility compared to a perfect crystal lattice. Addressing these challenges is crucial to realizing the full potential of diamond-based electronic devices.
Diamond Semiconductor Engineering
We employ advanced techniques such as Monte Carlo and Molecular Modeling Ion Beam Modification, starting with high-quality single crystal or microcrystalline diamond, meticulously refined to minimize intrinsic and extrinsic defects. This process methodically controls the modeled topological structure and the performance of the resulting materials associated with the targeted electronic application.
