Abstract

The proton conductivity of KH₂PO₄ (KDP) was modified by means of proton irradiation. Our neutron diffraction and high-resolution ¹H nuclear magnetic resonance measurements indicate that modification in the O ⋯ O bond length in the KDP system induced by the proton-beam treatment is responsible for the change in the proton conduction, which is accompanied by a reduction in the proton-hopping activation energy.
