Spin of nano-accoustic wave (IMAGE)
Caption
Representation of the spin of a nano-acoustic wave. This propagates in a nanowire lying on a piezoelectric material. The small arrows symbolise the direction and strength of the gyrating electric field. The large arrows at the top show the direction of propagation and the transverse spin of the sound wave. The colour coding in the nanowire or in the crystal indicates the piezoelectric potential (blue: minimum, red: maximum).
