Boron-doped single-crystal diamond has widespread applications in optoelectronics

Diamond is widely considered the ultimate power semiconductor, potentially revolutionizing power electronics and radio frequency electronics. Diamond itself is an insulator, and doping is crucial for enhancing its electrical properties. N-doped single-crystal diamond combines the conductive properties of p-type semiconductors with the excellent physical and chemical properties of diamond itself.

Boron-doped single-crystal diamond has a wide range of applications in optoelectronic devices.

Ultraviolet light-emitting devices: Diamond, with its wide bandgap and high breakdown field strength, is an ideal semiconductor UV light-emitting material. Using techniques such as boron doping, diamond UV light-emitting diodes (LEDs) have been successfully developed using homoepitaxial and heteroepitaxial growth, as well as heterojunction UV light-emitting diodes formed by combining diamond with other broadband semiconductors. These devices hold significant potential in optoelectronic devices and can be used in applications such as UV communications, optical storage, and optical sensors, including high-density information storage, UV detection, and biomedical imaging. 

Light detectors: Boron-doped diamond single crystals can be used to make high-performance light detectors with advantages such as high sensitivity, fast response, and low noise. They perform well in the fields of ultraviolet light detection and X-ray detection, and can be used in many fields such as environmental monitoring, medical imaging, and industrial testing, enabling efficient detection and conversion of weak light signals. Quantum technology field.

Quantum Computing and Quantum Sensing: High-purity boron-doped single-crystal diamond can be used to fabricate quantum bits (qubits), which exhibit long coherence times and high quantum state manipulation precision, making them a key physical medium for quantum computing. Furthermore, quantum sensors based on diamond nitrogen-vacancy color centers, optimized through boron doping and other techniques, can enhance their sensitivity and resolution. These sensors can be used for high-precision measurements of physical quantities such as magnetic fields, electric fields, and temperature, offering significant potential applications in quantum communication security, electromagnetic field detection, and biomedical testing.

Quantum secure communication: By utilizing the quantum properties of boron-doped single-crystal diamond, quantum secure communication devices based on single-photon emission can be developed, providing a higher level of protection for information security and realizing unconditionally secure communication methods. It has broad application prospects in fields with extremely high requirements for information security, such as military, finance, and government affairs.
