Jian "(Jack)" Zhou, Ph.D.
Senior Associate
Materials & Corrosion Engineering
  • Shanghai

Dr. Zhou’s areas of expertise include failure analysis, materials science, and nanoelectronics. He has extensive experience with magnetic thin films and semiconductors. With over 5 years of hands-on experience with electronic device fabrication in a clean-room environment, he is capable of solving a wide range of electronics failure problems utilizing his in-depth understanding of both materials and device-level issues.

Dr. Zhou specializes in a variety of materials-related issues in the area of consumer electronics, including display glass fracture analyses, brittle/ductile material failure analysis and related process contamination issues. He has significant experience analyzing defects in light emitting diodes (LED), including evaluation of the performance degradation over time. In addition, Dr. Zhou is experienced in the analysis of coating materials and failure analysis of a wide range of coating process-related issues.

Prior to joining Exponent, he was a Graduate Research Assistant in the Materials Science & Engineering department of UC Berkeley (co-advised by Professor R. Ramesh and Professor J. Wu), where he received his doctoral degree in 2014. His thesis work focused on exploring the electronic properties of ultra-thin semiconductor materials, down to single-molecule thickness. This included the synthesis of ultra-thin semiconductor materials, such as monolayer-thick MoS2, WSe2 and ReS2, as well as fabrication of nano/micro-electronic devices. He is familiar with a wide range of materials characterization techniques, including SEM, TEM, AFM, Raman spectroscopy, FTIR, DSC, GC-MS, and XRD.
