The mechanical hardness of grown KHOOD single crystal was performed using Vickers microhardness tester and investigated for different loads starting from 10 g to 100 g and it was decided to include under hard material category. The mechanical parameters such as elastic stiffness and yield strength were calculated and discussed in detail. Temperature dependent I-V, dielectric studies were performed and explained in detail. © 2020 Elsevier B.V.Article
