Dr Andreas Markwitz is Principal Scientist and Department Head at GNS Science. His ongoing interests in nanotechnology and advanced matererials are in silicon nanosurface, interfaces and how our understanding of new materials can be applied to industrial products.

Andreas has more than 200 publications in the field and has pioneered electron beam annealing and ion implantation at GNS under ultrahigh vacuum conditions. He has developed three ion implanters for implanting all elements of the periodic table with energies from 100 V to more than 100 kV and developed an electron beam annealer that can reproducibly manufacture nanosurfaces on the 1 nm scale.

Andreas’ interest in applying his surface science to industrial projects has led him to be involved in the Materials Accelerator at Auckland University and research with the Titanium Development Association in Tauranga.

Funding boost will help joint science projects with iwi groups

Project leader (MacDiarmid Institute Principal Investigator) Andreas Markwitz, of GNS Science, said findings would lead to an improved understanding of the health effects of volcanic eruptions and geothermal events in the central North Island. “The improved knowledge and understanding will help to underpin health monitoring and support geothermal and Māori tourism. It will also help […]

Next generation semiconductor materials and devices (Allen, Alkaisi, Markwitz, Zulicke, Blaikie)

These are rapidly gaining an international profile as highly functional materials with the potential to deliver “next generation” semiconductor devices in UV optoelectronics, transparent electronics for solar cells and displays, high frequency/high temperature power electronics, and in nanoarchitecture due to their dramatic range of spontaneous polarisation induced nanostructures. Our semiconductor fabrication expertise gives us the […]


Electron Beam Annealer for UHV Triple Beam Line System

The MacDiarmid funding paid for the revamp and allowed the system to get up and running in as short a time frame as possible. About the Instrument: The system consists of three beam lines feeding in at different angles to a central ultra-high-vacuum chamber. The first beam line is an ion implanter to shoot an […]

Andreas Markwitz – An Exploring Person

  Andreas’ research, as Principal Scientist at GNS Science, focuses on silicon nanosurface interfaces, and how our understanding of new materials can be applied to industry. He is a pioneer of electron beam annealing, which can manufacture surfaces on the 1nm scale, and his work with industry has allowed him an understanding of the critical […]

Chance Only Favours the Prepared Mind

Looking back at eleven years of the MacDiarmid Institute for Advanced Materials and Nanotechnology   “When you’ve got the equipment, the expertise, and the space to think about problems in a different way, the research almost tells its own story.”   Popular culture delights in the concept of scientific serendipity: Alexander Fleming discovering penicillin after […]

The Miniature World of Silicon Nanowhiskers

  In today’s modern society, rapid advances in technology are an everyday event, both in our day to day lives, and in industry. This reliance on high-tech equipment means there is a constant quest for electronic devices to be improved – to be made smaller, more portable, or more efficient. A large part of achieving […]
