Title: Microwave AC conductivity of domain walls

Abstract

Microwave AC conductivity may be improved or tuned in a material, for example, a dielectric or semiconductor material, by manipulating domain wall morphology in the material. Domain walls may be created, erased or reconfigured to control the AC conductivity, for example, for crafting circuit elements. The density and placement of domain walls may increase or decrease the AC conductivity and may control AC conduction pathways through the material. An electric potential applied to the material's surface may create a desired pattern of domain walls to meet desired AC conductivity criteria. Incline angle of the domain walls may be modified relative to a crystallographic axis of the material to temporarily or permanently modify or gate AC conductivity of the material. For example, the AC conductivity of the material may be gated by domain wall incline angle to increase, decrease or throttle current flowing through the material for an electronic circuit element.
