Computing at the Speed of Light with GaAs Nanowire Lasers - December 2013

 

Faster, smaller electronics are one step closer with researchers from The Australian National University successfully making the first room temperature lasers from gallium arsenide (GaAs) nanowires. These wires and lasers will lead to faster, lighter computers as light travels faster than electrons allowing data to be processed much faster. Dhruv Saxena, a PhD student at the Department of Electronic Materials Engineering (EME), has just co-authored a paper with Dr Sudha Mokkapati, an ANU-based ARC Super Science Fellow (also at EME), that has been published in NATURE PHOTONICS explaining how to make smaller lasers using GaAs nanowires – solid wires a few billionths of a metre in diameter.

Persistence Pays Off for WA Node - December 2013

 

The long lasting efforts of the WA Node of the ANFF to secure financial support from the Western Australian State Government has paid off. The Office of Science within the Department of the Premier and Cabinet of the WA Government announced that, as part of Innovation Co-investment Program, it will support the ANFF initiative in WA with $150,000 over the 18 month Federal Government Collaborative Research Infrastructure Scheme (CRIS) period from 1 July 2013 to 30 June 2015.

ACT Node welcomes our new MOCVD Process Engineer! - December 2013

 

The ANFF ACT Node has just appointed Mykhaylo Lysevych as the Process Engineer to look after the newly installed (and old) MOCVD reactors. Mykhaylo completed his Bachelor of Engineering in Electronic Engineering (Laser and Optoelectronic Systems) in 2003 at Lviv Polytechnic National University in the Ukraine and, in 2005, joined the Department of Electronic Materials Engineering (EME) at The Australian National University as an MPhil student working on “Design, Growth, Fabrication and Characterisation of AlInGaAs/InP Lasers”.

Selective Area Epitaxy of InP Nanowires - September 2013

 

Semiconductor nanowires are currently of great research interest due to their unique properties. Axial and radial heterostructure nanowires (NWs) have been proposed as nano-building blocks for next generation electronic and photonic devices. These devices are expected to revolutionise our technological world in the way of new devices and components. For more details click here.

 

 

User Satisfaction Survey 2013 - September 2013

 

Each year we invite users of our facility to participate in a User Satisfaction Survey to gauge our effectiveness in three key areas – service, communication and accessibility. It also provides an opportunity for users to give valuable feedback through additional comments and suggestions to improve the overall experience of accessing this valuable research facility.

First Annual User Workshop - September 2013

 

The ACT Node held their first User Workshop on Tuesday, 25 June - only a couple of weeks after the last newsletter was sent out. It was a well attended event, with close to 60 people, held in the Leonard Huxley Lecture Theatre with a total of 11 presentations - a full digest of the abstracts is available here.

An Artificial Nose! - Explained in Two Minutes - June 2013

 

Gino Putrino is a PhD student at the University of Western Australia and one of 12 winners of a world-wide competition for researchers to reduce their work to simple visual ideas that can be understood by everybody. Gino was the only West Australian finalist chosen from among more than 200 competitors that entered an international 'PhD TV 2 Minute Thesis' contest. Gino's project attempts to bring together vibrating mechanical beams, lasers, and butterfly wings to aid in the early detection of lung cancer. Read more here.

 

 

Latest Tool Arrival - JA Woollam M-2000D Spectral Ellipsometer - June 2013

 

The ACT Node has recently taken delivery and commissioned a new piece of kit in our EBL Laboratory - a Spectral Ellipsometer. The JA Woollam M2000D Ellipsometer allows accurate measurements of refractive index and thickness of various types of layers spanning dielectrics, semi-conductors and thin metal films.

Nanoantennas: Manipulating Light at the Nanoscale - March 2013

 

Antennas are all around in our modern wireless society: they are the front-ends in satellites, cell-phones, laptops and other devices establishing communication by sending and receiving electromagnetic waves. While all these devices typically operate at frequencies from 300 GHz to as low as 3 kHz, according to Maxwell's equations the same principles of directing and receiving electromagnetic waves should work at various scales independently of the wavelength. Thus, one may naturally ask "Can an antenna send a beam of light?" And the answer is "Yes, a nanoantenna can!" Read more here.

 

 

State-of-the-Art Thin Film Deposition Tool Transferred to WA Node - March 2013

 

With the aid of the Educational Investment Fund (EIF), ANFF-Qld acquired a state-of-the-art thin film deposition tool which was subsequently transferred to the WA Node. A Sentech SI 500D Inductively Coupled Plasma Enhanced Chemical Vapour Deposition (ICPECVD) system was supplied from Germany by SENTECH Instruments GmbH and represents the leading edge for plasma deposition.
