Education:

 

  • Ph.D., Institute of Crystal Materials, Shandong University, China, 2000
  • M.S., Shandong University, China, 1997, (Chemistry)
  • B.S., Shandong University, China, 1994, (Chemistry)

 

Research Interests:

 

  • Growth of single crystals, including optical, ferroelectric, and piezoelectric crystals
  • High temperature, high power piezoelectric materials, including lead free
  • Relationship of material properties and microstructure

 

Dr. Zhang is interested in the crystal growth of nonlinear optical, laser, ferroelectric, and piezoelectric single crystals by Bridgman, Flux, and Czochralski techniques; also in the field of high temperature, high performance, and high power ferroelectric crystals and ceramics, including lead-free materials. He characterizes the electrical properties of ferroelectric materials (crystal, ceramic, and composite) under different temperature, external dc bias, and stress, to try to understand the process-structure-property relationship.
