Phone: (301) 405-5220
Dr. Salamanca-Riba's research is in the areas of multiferroic nanocomposites, DNA-based biosensors and radiation sensors on GaAs, semiconductor nanowires, and self-assembly for the formation of nanocomposite materials and structures.
Dr. Salamanca-Riba is also a member of the Materials Research Science and Engineering Center (MRSEC). Her research at the MRSEC is on the relation between processing parameters, structure and properties of oxide-based multiferroic materials. Her research involves the use of the transmission electron microscopes and the atomic force microscope at the Nanoscale Imaging, Spectroscopy, and Properties (NISP) Laboratory.
Her project on DNA attached to GaAs aims at understanding the anchoring mechanism between thiolated DNA and GaAs that gives rise to arrays of single stranded DNA molecules oriented normal to the surface of GaAs. These structures could be used for the fabrication of biosensors and radiation sensors.
Her third project is in the growth and characterization of semiconductor nanowire arrays of ZnO for the fabrication of light emitting devices.

Dr. Salamanca-Riba typically teaches the following courses:
- ENMA 671: Defects in Materials
This course emphasizes fundamental aspects of zero-, one- and two-dimensional defects in materials. The thermodynamic equilibrium of point defects in different oxide materials and their effect on the physical properties of the material are discussed. Dislocation-dislocation and dislocation-point defect interactions, dislocations in different crystals and roles of dislocations in deformation, twinning, and phase transformation are also discussed. The effects of dislocations and other defects on the electrical, optical and thermal properties of materials are discussed.
- ENMA 680: Experimental Methods in Materials Science
This course covers the basic principles of electron microscopy theory, electron diffraction, and imaging theory. The electron beam sample interaction that gives rise to different signals is related to the structural and compositional information that is obtained from a sample using a TEM. The most common TEM techniques for structural characterization of a sample, namely, electron diffraction, bright/dark field imaging, and high resolution lattice imaging are discussed. Compositional information obtained from x-ray fluorescence and electron energy loss as well as the resolution of these techniques is also covered. A brief description of techniques used to study magnetic materials is also presented.
- ENMA 683: Special Problems in Materials Science, Structural Determination Laboratory
This course covers the operation of an electron microscope. TEM techniques that are used to characterize the structure, defects, and composition of a sample are presented and used to study a variety of materials. These techniques are: electron diffraction patterns, bright/dark field imaging, high resolution lattice imaging and energy dispersive X-ray spectroscopy. This course also covers different sample preparation techniques for TEM. The goal of the course is that the students become independent users of the TEM. The main objective in this class is to become an independent user of the TEM. This is achieved by learning:
- to align the beam in a transmission electron microscope
- to operate the TEM by
tilting the sample to the desired orientation
- taking a diffraction pattern
- taking bright/dark field images
- how to analyze the images
- to obtain energy dispersive X-ray spectra
- to obtain high resolution lattice images
