PROFESSIONAL EXPERIENCE

MICRON TECHNOLOGY INC. – Longmont, CO

Senior Research Chemist, 05/2009 – 08/2012

Enabled new products through materials R&D, improved materials-related performance (e.g., speed, brightness, robustness,

and lifetime) of microdisplay products, and solved pressing materials-related problems occurring in commercial mixtures.

Selected contributions:

Led 3 chemists and 1 engineer to conduct materials R&D including synthesis and characterization of >100 ferroelectric

liquid crystals (FLCs) containing heterocycles (e.g., pyridine, pyrimidine, oxadiazole, thiadiazole, pyridazine, etc.) and

LC surfactant polymers, mixture formulation, and dielectric spectroscopy measurements.

Invented ionic surfactants and formulated mixtures therewith, solving FLCOS microdisplay problems (e.g., image sticking

and defect formation) under dc-unbalanced drive and enabling 50% brighter FLCOS microdisplays.

Developed efficient chemical process methods for manufacturing of 6 commercial FLC components, ending a supply

crisis of a commercial mixture used in a multi-million unit electronic view-finder market (~$50M).

DISPLAYTECH INC. – Longmont, CO (Acquired by MICRON in 05/2009)

Senior Research Scientist, 01/2005 – 05/2009

Designed, synthesized, and formulated EO materials for nonlinear optics (NLOs) and organic photovoltaics (OPV)

applications. Provided on-going production support including troubleshooting and problem-solving. Managed NSF projects

carried out in a multidisciplinary team consisting of chemists, physicists, and engineers.

Selected contributions:

Synthesized FLC monomers with acrylate or methacrylate termini and their side-chain and main-chain polymers by UV-

curing process, hydrosilylation reaction, and acylic diene metathesis (ADMET) polymerization.

Designed and prepared >50 novel dimer, trimer, oligomer, and polymer FLCs incorporating dyes into their structures

and formulated mixtures used for NLO and OPV applications.

Yongqiang Zhang 2

Developed polymer-dispersed FLCs, epoxy polymers, and acrylic urethane polymers for bistable display application and

fluorine-containing polyimides for FLC alignment layers.

Synthesized >200 bent-core LCs and formulated mixtures therewith for high performance optical phase modulation.

Developed efficient chemical process approaches to manufacturing commercial chiral FLCs, ending a supply crisis of a

commercial mixture (a multi-million dollar market) due to the loss of an FLC component supplier.

Fabricated LC cells with ITO patterns using photolithography (positive and negative photoresist processes).

W rote 4 NSF SBIR proposals on organic materials and had 3 funded (2 Phase I and 1 Phase II, total $700,000).

As project manager and principal investigator (PI), managed four NSF-supported multi-disciplinary SBIR projects

($1,200,000) which involved chemists, physicists, and engineers.
