Acceleration of Kirkendall effect processes in silicon nanospheres using magnetic fields. Issue 6 (26th January 2018) - Bian, Yuecheng
Abstract : We show that a magnetic field can act as an independent parameter to accelerate the Kirkendall effect in a liquid reaction system. Abstract : We show for the first time that a magnetic field can act as an independent parameter to accelerate the Kirkendall effect in a liquid reaction system. By taking silicon-based nanospheres as a model, it was demonstrated that a magnetic field could efficiently reduce the time of the Kirkendall effect processes at relatively low reaction temperatures. The hollow structure of the product obtained after 5 h under a magnetic field of 1 T is the same as that obtained after 24 h without a magnetic field.
