Charles Tu and H. H. Wieder are involved with the epitaxial layer growth of heterojunctions, quantum wells and superlattices of binary and ternary III-V compound semiconductiong alloys. Huey L. Luo and his group are working with high transition temperature superconducting oxide systems. Their studies include deposition, analysis and processing of thin films for IR and microwave devices. Their studies include nanostructured magnetic materials, magneto-optic spectroscopy and magnetically tunable optoelectronic devices. Neal Bertram's conducts research in magnetic recording phenomena in association with the Center for Magnetic Recording Research.
Materials characterization is carried out by a range of techniques within the department.
It is used to determine the microstructural, electrical, electro-optic, galvanomagnetic and optical properties of bulk layers, heterojunctions, quantum wells and superlattices. Karen Kavanagh's research focuses on the development of mechanisms for atomic diffusion in III-V semiconductors, understanding plastic relaxation at semiconductor interfaces and the effect of local structure on semiconductor surface barriers. Lea Rudee is investigating the structural properties of magnetic materials using a number of techniques including transmission electron microscopy. S. S. Lau and his associates are working on ion beam processing of electronic and optoelectronic materials. Ed Yu's group is investigating the atomic-scale properties of semiconductor heterostructures and devices using scanning tunneling microscopy.
