Modulated acoustic phonons and their interactions with electrons in a coated cylindrical silicon nanowire (SiNW) are investigated theoretically. The impact of acoustic phonons on the interactions is encapsulated in the form factor. The form factor for a SiO2-coated SiNW is larger than that calculated using bulk phonons while that for a HfO2-coated SiNW is smaller, when the coating shell thickness is sufficiently large. This result can be qualitatively explained by the relationship of acoustic impedance between the nanowire core and shell. The form factor reduction directly weakens the interactions, and thereby provides higher electron mobility than that limited by bulk phonons.
