Recent theoretical studies at Monash University bring us a step closer to realistic ‘quantum batteries’. Such technology would depend on the energy difference offered by different quantum states, rather than on electrochemical changes, as is the case in traditional batteries. Quantum batteries also offer potential for vastly better thermodynamic efficiency, and ultra-fast charging time. The study, which was co-led by …
Wait. What do you mean ‘transistors’? Yep, ‘transistors’ are still the basis of electronics. In essence, they’re the tiny controllable switches that form the building blocks of logic circuits, switching between open (0) and closed (1). In your Dad’s old ‘wireless’ radio, transistors were the small metallic components shaped like War of the Worlds war tripods. Those replaced the glass …
Applying an electric field switches conduction mode of a topological material FLEET researchers achieved a significant landmark in the search for a functional topological transistor in 2017, using an applied electric field to switch the electronic conduction mode of a topological material. A ‘gate’ electrode was used to switch the conduction mode in the topological material Na3Bi. Na3Bi is a …

The tour included the experimental laboratories of FLEET Chief Investigators Michael Fuhrer, Agustin Schiffrin, Kris Helmerson and Qiaoliang Bao. Members saw where: Michael Fuhrer grows atomically-thin (2D) materials in the lab using …
UNSW researchers solve a 10-year-old mystery in the way nanoscale transistors work. Half of all the transistors in your iPhone use positively-charged ‘holes’, rather than negatively-charged electrons to operate. At university, we teach undergraduates that holes are quasiparticles, basically ‘missing electrons’ – a bit like the bubble in a spirit level, or the missing chair in a game of musical …
A variety of methods exist to deposit atomically-thin (two-dimensional) crystals. But large-scale deposition has remained a challenge. However a recent RMIT-led study has found success with a new technique with potential to open new doors for two-dimensional semiconductors. The discovery has been described as a ‘once-in-a-decade’ advance. The new technique introduces room-temperature liquid metals (gallium-based) as a successful reaction environment …
