Summary
Chemical Vapour Deposition (CVD) of diamond thin films faced early hurdles in semiconductor applications due to wafer size and doping challenges. Recent discoveries in quantum computing and materials science have reignited interest in diamond technology.
Area of Science:
- Materials Science
- Semiconductor Technology
- Quantum Computing
Background:
- Diamond thin film technology using Chemical Vapour Deposition (CVD) generated significant excitement in the 1990s for its potential semiconductor applications.
- Early challenges, including difficulties in producing large-area diamond wafers and achieving effective n-type doping, significantly slowed progress and reduced research funding.
- Despite initial setbacks, recent breakthroughs in the 2010s have revitalized the field, highlighting new applications and renewed hope for diamond's technological promise.
Purpose of the Study:
- To provide an updated review of diamond thin film technology, assessing progress over the past 25 years.
- To analyze the reasons behind the slowed development of diamond-based electronics.
- To highlight recent advancements and emerging applications driving a resurgence in diamond research.
Main Methods:
- Review of historical research and development in chemical vapour deposition (CVD) of diamond thin films.
- Analysis of challenges in large-area wafer fabrication and n-type doping of diamond.
- Identification and discussion of recent game-changing applications discovered since the early 2010s.
Main Results:
- Initial high expectations for diamond semiconductors were tempered by significant material processing and doping challenges.
- A decline in research enthusiasm and funding occurred as competing materials advanced.
- New applications in electrochemical electrodes, nitrogen-vacancy (NV) centers for quantum computing, and gemstone-quality diamond growth have spurred a revival.
Conclusions:
- Diamond thin film technology has experienced a complex trajectory, marked by initial promise, substantial obstacles, and a recent resurgence.
