Modern electronic devices and circuits are intricately complex structures consisting of semiconductors, metals, and dielectrics and the interfaces between them.   Their performance and reliability sensitively depends not only on the design and materials selection but also the processing techniques used. Professor Skowronski's research covers a wide range of issues in this technology including: crystal growth of semiconductors; deposition of thin films of metals, semiconductors, and dielectrics; characterization of processing-induced defects; and degradation phenomena in electronic devices. The unifying theme of his research is the relationship between process conditions and device performance. Prof. Skowronski's research projects attempt to balance two distinctly different goals: the demonstration of novel approaches to processing of materials and the development of fundamental understanding of materials and devices.

The overarching goal for the group's research is the development  and discovery the materials, phenomena, and devices for energy efficient computing. Within this field the currently active projects focus on:

(i) synthesis of novel electronic materials such as binary and complex oxides, amorphous chalcogenide alloys and 2D materials.
(ii) imaging of processes in electronic devices under bias
(iii) design, fabrication, testing and simulation of electronic devices for applications as memory cells, selection devices, and oscillators
