Go-to Guy for Ultra-Pure hBN Crystals: Interview with WPI-MANA Researcher
TSUKUBA, Japan, Mar. 24, 2021 /Kyodo JBN-AsiaNet/ --

Dr. Takashi Taniguchi is renowned for high-pressure synthesis of hBN (hexagonal 
boron nitride) crystals, a key material in nanotechnology research. His 
ultra-pure hBN crystals have the highest quality available, and they have been 
attracting the attention of researchers around the world, contributing to a 
variety of research into two-dimensional materials in the fields of quantum 
physics and quantum devices, including graphene research.

Q. You're world-famous for your hBN crystals. Why are you the go-to guy for 
this material? 

"Mostly it's just a result of luck and good circumstances, especially having 
access to our beautiful 30,000-ton hydraulic press. But more importantly, for 
more than 10 years I have had the freedom to concentrate on this work, to keep 
the momentum and direction, using very nice facilities. Being able to 
monopolize the equipment is a huge benefit -- such a situation is not easy to 
come by. 
I have been studying single crystal growth under high pressure for more than 20 
years now. High-purity crystals can be obtained using facilities like these, 
including our press, and I have sole use of them. 
Also, as a NIMS researcher, I have a big advantage over university people -- no 
lecturing responsibilities -- and that frees up a lot of time, which I can put 
into my research. Of course, this is a national lab. So there are some big 
projects I participate in. But there's also freedom to do other things of 
interest."

Q. What are the crystals used for?

"They're mostly used by researchers studying graphene. As you probably know, 
graphene is a monolayer of graphite, a single layer of carbon atoms arranged in 
a two-dimensional hexagonal lattice. It conducts electricity and heat with 
impressive efficiency. So it is being used in quantum transport research, and 
we expect lots of applications, including anti-corrosion coatings, sensors, 
electronics, flexible displays, solar panels, DNA sequencing, drug delivery -- 
all kinds of things...."
