Development of n-Type Diamonds for Practical Use in Diamond Semiconductors also Making Advances

TOKYO, March 4, 2025 /PRNewswire/ — Orbray has developed production technology for the world’s largest self-standing single-crystal (111) diamond substrates, measuring 20mm square. This achievement marks significant steps in advancing diamond-based quantum devices and power devices. The company aims to commercialize large (111) diamond substrates by 2026 and is also actively working on the development of n-type self-standing diamond substrates, a crucial component for making diamond semiconductor devices mainstream.

Diamond semiconductors are being developed for a wide range of applications due to their exceptional properties. In recent years, there has been significant progress in increasing the size and improving the quality of diamond substrates to meet growing industry demand. High-quality (111) diamond substrates have drawn particular interest in the development of diamond quantum devices that contain nitrogen-vacancy (NV) centers. Additionally, (111) diamond substrates are regarded as essential not only for quantum applications but also for achieving high-performance n-type diamond-based devices, including diamond power devices. However, until now, only small-scale (111) diamond substrates, approximately 3mm square, have been available. (111) diamond crystals were prone to defects known as twin crystals during CVD growth, posing significant challenges to the production of large-diameter and thick single-crystal diamond crystals.

In a September 9, 2021 press release, Orbray Co., Ltd., announced the successful development of a high-quality, 2-inch diameter (100) self-standing diamond substrate using its proprietary efficient step-flow growth method (https://orbray.com/magazine_en/archives/811https://orbray.com/magazine_en/archives/1401). Building on this diamond crystal growth technology and utilizing specially designed sapphire substrates, the company has been advancing the development of a (111) single-crystal diamond self-standing substrate.

This work has culminated in the successful synthesis of a 20mm square (111) single-crystal diamond self-standing substrate without twin defects.

Orbray plans to commercialize this technology by 2026. This advancement is expected to drive progress in the development of diamond semiconductor devices.

Greenzie releases 2025 Annual Safety Report, documenting multi-year safety performance at commercial scale

Published

on

By

The data shows zero lost-time injuries, zero OSHA medical attentions and zero human near-misses across real-world operation

ATLANTA, April 23, 2026 /PRNewswire/ — Greenzie, the technology platform powering commercial autonomy across multiple OEMs, today shared multi-year safety data from real-world commercial operation, documenting more than 150,000 autonomous miles with zero lost-time injuries, zero OSHA medical attentions and zero human near-misses. The data is published in Greenzie’s 2025 Annual Safety Report, available at greenzie.com/safety.

The report is based on extensive operational data spanning more than 5.4 billion square feet of turf mowed, 68,000+ hours of autonomous mowing and more than 50,000 operator days, the equivalent of 265 mowing seasons.

“Greenzie is helping define safety in autonomous landscape operations, and transparency is a critical part of that,” said Steve Bush, chief operating officer of Greenzie. “These results show that commercial autonomy is operating safely at meaningful scale in the field. Transparency matters because as this category matures, real-world data helps build confidence in what responsible deployment looks like.”

The report’s findings are particularly significant in the context of the U.S. landscaping industry, which employs roughly 1.3 million workers and experiences a higher-than-average rate of workplace accidents compared to other fields. Greenzie’s multi-year operating data shows that autonomy is not theoretical; it is already being deployed consistently and performing safely at scale.

“Greenzie Powered Autonomy™ has been validated through years of sustained use in the field,” Bush said. “That level of real-world performance reinforces both the reliability of our platform and the broader readiness of commercial autonomy.”

Greenzie attributes this performance to a disciplined safety approach that includes robust perception, tested operating standards and continuous validation in real-world commercial environments.

About Greenzie

Founded in 2018, Greenzie is the technology platform powering commercial autonomy. Created to solve the landscape industry’s labor and productivity challenges, Greenzie works with leading equipment manufacturers to deliver the software, navigation and safety systems that enable mowing and other outdoor power equipment to operate autonomously in real-world commercial environments. Today, Greenzie’s platform is running on hundreds of machines in active use, helping manufacturers bring autonomy to market and allowing operators to get more done with limited labor—moving autonomy from early experimentation to everyday operations.
