About

Growth, measurement, and the gap between them

My work sits between synthesis and metrology. I grow atomically thin carbon, then I measure it carefully enough to know whether it will actually do the job — and most of my published results come from the disagreement between those two halves.

I started in scanning probe microscopy at the Institute of Solid State Physics in Moscow, building carbon-nanotube probes because the commercial ones weren't sharp enough for what we wanted to see. That set a pattern. A few years later I was trying to pattern electrodes onto bacterial nanofilaments to measure charge transport along them, and conventional lithography destroyed every sample. So we developed a resist chemistry that doesn't — a chitosan-based, water-processable route that became a patent and a line of work on gentle patterning for delicate and bio-organic materials.

The same instinct carried into growth. Standard graphene CVD needs hydrogen and low pressure; we found an ambient-pressure Boudouard route that produces millimetre-scale crystals without either. Then at NUS the material changed but the question didn't. Monolayer amorphous carbon is a continuous random network of five-, six-, and seven-membered rings — no grain boundaries, because there are no grains. That structural disorder turns out to be a feature: it lowers the dielectric constant, it makes the surface lithiophilic, it binds to copper far better than graphene does, and it activates a basal plane that in graphene is inert.

Since 2022 that platform has moved from a curiosity to something semiconductor manufacturers run in their own fabs. I am part of the core experimental team on the NUS interconnect program, and I mentor the Ph.D. students who carry individual threads of it — several of whom are now joint first authors with me.

Research

Four threads

Each is a material problem first and a physics problem second. Representative papers are linked below each.

01

Monolayer amorphous carbon

A 2D solid with no grains

A continuous random network of 5-, 6-, and 7-membered rings, grown layer by layer. Because it has no grain boundaries it behaves as a genuinely uniform ultrathin film — which is what makes it useful as a diffusion barrier and as an ultralow-k dielectric for advanced interconnects. The underlying physics is still open: we see relativistic quasiparticles and signatures of quantum criticality in a material that has no periodic lattice at all.

02

Interfaces and devices

What happens at the contact

A 2D film is only as good as the thing it touches. Amorphous carbon adheres to copper markedly better than graphene does, which is what makes it viable in a metallisation stack. Its disorder makes the surface lithiophilic, so lithium nucleates across it rather than at a few runaway sites. And it works as a hard-disk overcoat below 2 nm, where every existing carbon coating fails. Same material, four industries.

03

Nanofabrication

Patterning things that don't survive patterning

Solvents, plasma, and heat destroy bio-organic samples and many soft nanomaterials long before you can measure them. I develop resist chemistries and process flows that avoid all three — water-processable chitosan resists, liquid-free patterning of nanotube films, AFM-based lithography on van der Waals heterostructures. The environmental argument came later and turned out to be just as strong.

04

Growth & transport

Making it, then proving it

Ambient-pressure graphene CVD via the Boudouard reaction, without hydrogen; controlled densification of single-walled nanotube films; terahertz, infrared, and impedance spectroscopy to get at charge transport in systems from nanotube networks to single bacterial filaments. This is the toolkit the other three threads depend on.

Capabilities

Hands-on nanotechnology

Thirteen years at the bench in three areas. Growing carbon, patterning things that resist being patterned, and measuring the result with a scanning probe.

CVD growth of carbon

Graphene by ambient-pressure, hydrogen-free routes; layer-by-layer amorphous carbon; aerosol CVD of nanotubes with reactor design and tuning.

Advanced nanolithography

Electron-beam, optical and AFM-based patterning — plus biocompatible resists and liquid-free routes for materials that conventional processing destroys.

Scanning probe microscopy

PeakForce QNM nanomechanics, MFM, STM — and in-house carbon-nanotube probe fabrication when commercial tips aren't good enough.

Industry & IP

Work that left the lab

I am part of the core experimental team on an advanced-interconnect materials program at NUS. Results from that team on atomically thin carbon led to a joint development project with a major semiconductor manufacturer, and to further joint research with several equipment and device makers in the same program. My role is experimental: growth, scanning-probe and spectroscopic characterisation, and the application studies that establish whether a film meets a real specification.

Partners and project scope are under NDA, so I don't name them here. The public disclosures are the ultralow-k dielectric paper accepted at Nature Electronics and the patent below.

Consulting

Work with me

I take a small number of external engagements alongside my research. They tend to be short, technical, and decision-driven — someone needs to know whether a material or a process will hold up, and needs an answer they can act on. The underlying techniques are set out on the capabilities page.

01

Process & materials development

Getting a 2D or thin-film material out of a paper and into a process flow that survives contact with reality.

  • CVD process design and troubleshooting — graphene, amorphous carbon, nanotube films
  • Transfer, stacking, and patterning routes for films that damage easily
  • Resist and lithography selection for delicate, soft, or bio-organic substrates
  • Scale-up questions: what breaks when you leave the coupon and go to a wafer
02

Characterisation & failure analysis

Measuring what a film actually is, and working out why an interface failed.

  • AFM and scanning probe: PeakForce QNM nanomechanics, MFM, STM
  • Adhesion, delamination, and interface failure in thin-film stacks
  • Terahertz–infrared and impedance spectroscopy; charge transport and noise
  • Second opinion on existing datasets — reading someone else's micrographs and spectra
03

Technical due diligence

For investors, corporate development teams, and programme managers who need a claim checked by someone who has run the experiment.

  • Assessment of 2D-materials and nanocarbon claims — what is real, what is years away
  • Literature and patent landscape review in carbon and 2D materials
  • Technology scouting and expert review of research proposals
  • Written findings, or a call with your technical team

Start with a short call

Thirty minutes, no charge, to work out whether I'm the right person for the problem. If I'm not, I will usually know who is.

Engagements are typically scoped by the day or as a fixed-price review. Work involving my NUS position is subject to institutional approval and existing confidentiality obligations; I will tell you up front if a topic is one I cannot take. I do not accept work that conflicts with the industry programs described above.
