A team of researchers from the University of Manchester’s
Photon Science Institute have collaborated with colleagues from the University
of Cambridge and industry partners from Germany to develop the new instrument
of electronic devices employing 2D materials reports ITRealms.
This table-top instrument, ITRealms gathered affords the new
magnet to only generate a field in short pulses that each last for a fleeting
one hundredth of a second.
ITRealms recalls that since the 1950s, experiments conducted with magnetic fields
have played a pivotal role in the development of semiconductors devices such as
transistors and light-emitting diodes that have changed the world. Previously,
scientists have had to visit huge facilities such as the National High Magnetic
Field Laboratory in the USA to probe the fundamental structure of materials to
better understand and manipulate their properties.
However, such facilities are
extremely scarce, and scientists must compete with others for valuable time on
the machines.
The team led by Dr Darren Graham, ITRealms reports worked
with researchers from manufacturers Laser Quantum to incorporate lasers into
the new instrument which are more than 10 times quicker than those found in
typical ultrafast laser systems. Thus allowing them to increase the number of
measurements during one magnetic pulse to around 100 - previous experiments
with a similar magnet system were limited to 4 measurements per pulse.
“We’re sure that when people realise that we can do such
measurements in the lab they will be lining up to use our instrument. We’ve
already been contacted by several groups interested in having measurements made
on their samples,” Dr Graham said.
Ben Spencer, a post-doctoral research associate at the
University of Manchester’s Photon Science Institute said, the challenge when
using these pulsed magnets was being able to record data within the brief time
period that the magnet is on.
“The breakthrough we have made is in the measurement
technique, which is the leap forward that will now enable routine cyclotron
resonance measurements on a table-top in a laboratory environment,” Spencer
said.
