Melbourne, March 13 : Studying whether the potential of music against the standard method of pulse generation in producing nanowires, an Australian researcher has found that silicon nanowires grow more densely when blasted with Deep Purple than any other music.
David Parlevliet, a PhD student at Murdoch University in Perth who is testing nanowires for their ability to absorb sunlight in the hope of developing solar cells from them, presented his findings at a recent Australian Research Council Nanotechnology Network symposium in Melbourne.
One method for growing the nanowires involves blasting a voltage through silane gas to produce a plasma that pulses on and off 1000 times a second. Over time, the process enables molecules from the gas to deposit on a glass slide in the form of a mesh of crystalline silicon nanowires.
Parlevliet is trying to develop a method to grow long and straight nanowires that cover the entire surface of the slide in a tight mesh, in order to ensure maximum absorption.
He says that he undertook the current study to investigate whether music could replace the usual method of generating the pulsed plasma.
"Instead of using the pulse from the pulse generator, I plugged the music player in," ABC Online quoted him as saying.
During the study, he tested the effect of Deep Purple's 'Smoke on the Water', Chopin's 'Nocturne Opus 9 No 1', Josh Abrahams' 'Addicted to Bass', Rammstein's 'Das Modell' and ABBA's 'Dancing Queen'. He even tested an ABC Dr Karl podcast for comparison.
The researcher observed that the mesh of nanowires deposited on his glass slide was most dense when he played them Deep Purple, and least dense when he played them music by the German metal band Rammstein.
"They didn't really like Rammstein very much, probably due to the volume differences in it," he said.
He, however, said that music did not produce a better crop of nanowires than the standard method of pulse generation.
"The kinkiest samples were produced by 'Smoke on the Water'," he said.
"The nanowires don't really like music as opposed to the standard signal," he added.
But still, Parlevliet believes that the use of music in growing nanowires may become significant if kinky nanowires find an application in future.
