Novel “converter” invented by NUS scientists heralds breakthrough in ultra-fast data processing at nanoscale

Invention bagged four patents and could potentially make microprocessor chips work 1,000 times faster

Advancement in nanoelectronics, which is the use of nanotechnology in electronic components, has been fueled by the ever-increasing need to shrink the size of electronic devices in a bid to produce smaller, faster and smarter gadgets such as computers, memory storage devices, displays and medical diagnostic tools.

While most advanced electronic devices are powered by photonics – which involves the use of photons to transmit information – photonic elements are usually large in size and this greatly limits their use in many advanced nanoelectronics systems.

Plasmons, which are waves of electrons that move along the surface of a metal after it is struck by photons, holds great promise for disruptive technologies in nanoelectronics. They are comparable to photons in terms of speed (they also travel with the speed of light), and they are much smaller. This unique property of plasmons makes them ideal for integration with nanoelectronics.

Space, the final frontier for Graphene and 2D Materials

Several years ago Prof. Castro Neto predicted the importance of graphene and other 2D materials on space technology and exploration: “In the space business weight is a big issue from the financial and physical perspectives. The heavier the payload the higher the cost of launching rockets and accelerating them into higher speeds. Graphene and 2D materials are the lightest functional materials in the universe and hence are perfect in terms of mass density”, says Prof. Castro Neto, “and, moreover, in the absence of air and water, 2D materials never corrode and can last indefinitely.”  Prof. Castro Neto goes further “In deep space the temperatures are so low that some 2D materials superconduct reducing the energy cost of operation to a perfect zero.”

Prof Castro Neto’s dreams of making graphene a big player in the space race are becoming reality. In collaboration with Boreal Space, a US based satellite launcher, CA2DM is soon launching the first graphene devices into orbit opening a new chapter in space exploration for 2D materials.

DPM Teo’s visit to CA2DM

Deputy Prime Minister and Chairman of National Research Foundation (NRF), Mr. Teo Chee Hean, accompanied by NUS President, Prof. Tan Chorh Chuan, the Permanent Secretary of NRF and Public Service Division, Ms. Yong Ying-I, and the CEO of NRF, Prof. Low Teck Seng, visited our Centre on 26 September 2017.

During the visit, Prof Antonio Castro Neto, Director of CA2DM and Prof Barbaros Oezyilmaz, Deputy Director (Translation) of CA2DM’s Office for Industry and Innovation (OII), shared with DPM Teo on the achievements of the Centre and how we translate scientific research to industry applications by supporting researchers to validate and benchmark their technologies and working closely with industry partners to identify graphene’s unique properties relevant for their needs.

First International Standard on Graphene Definitions has been published

Graphene is considered by many as a wonder material with the potential to revolutionize several industrial sectors: from coatings and composites, to electronics and aerospace. The estimated global market for graphene itself has been estimated to be in the range of US$ billions by 2035.Besides, a worldwide race is happening to develop graphene applications, with an even bigger market potential, reaching areas such as high efficiency batteries and desalination membranes. However, as any other new revolutionary material, the development of these applications and their introduction into the market depend strongly on the quality of the produced graphene.

and a group of distinguished ST Kinetics young engineers.
During the two hours visit Dr Lee had the opportunity to hear about the scientific and entrepreneurial activities at CA2DM and also visit CA2DM’s facilities.

This visit opens new venues for collaboration between ST Kinetics and CA2DM.

Grooming young scientists in Singapore

Research work on monolayer WS2 done by Belle Sow Miaoer, a student from NUS High School of Mathematics and Science, Dr Lu Junpeng (NUS) and Professor Sow Chorng Haur (NUS) was published and highlighted in the inside cover page of Advanced Optical Materials [1].

Monolayer WS2 is a promising material in optoelectronic devices. Decoration of WS2 using gold nanoparticles (AuNPs) produces surprising results. AuNPs exhibit preferential, site-selective decorations that reveal hidden heterogeneity within the WS2. In addition, the AuNPs enhance fluorescence intensity in selected regions and even activate fluorescence emission from previously dark regions. The photoluminescence spectra become sharpened and dominated by neutral excitons.
