Electric field-induced toughening in GaN piezoelectric semiconductor ceramics
In this paper, the effect of an applied electric field on fracture toughness of polarized GaN piezoelectric semiconductor ceramics was studied by using experimental and numerical methods. The results show that fracture toughness increases by 22% under a field intensity of 0.83 kV cm-1, and with furt...
