Magnetic and transport studies of Co doped TiO2 thin films

Lead Institution
Boise State University
Principal Investigator
Alex Punnoose
Project type
Exploratory Research
Thin films of Co doped TiO2 will be prepared using the MBE and sputter deposition facilities available at PNNL. The magnetic and transport properties of the samples will then be investigated using a…

Principal Investigator
Alex Punnoose
Project type
Exploratory Research
Our group at Boise State University is preparing powder and thin film samples of oxide semiconductors SnO2, TiO2 and ZnO doped with magnetic impurities to produce magnetism. In collaboration with Dr…

Multifunctional Nanostructures for Nano-Biotechnology Applications

Lead Institution
Boise State University
Principal Investigator
Alex Punnoose
Project type
Large-Scale EMSL Research
Our group at Boise State University is preparing powder and thin film samples of metla and metal oxide nanoparticles in pure and transition - metal - doped forms. We are also interested in preparing…

This activity involves extended that state of the art in surface analysis by expanding the understanding of equipment capability, testing new approaches to instrument calibration and operation, and…

Mossbauer Spectroscopic Investigations of Fe Doped SnO2 powders

Lead Institution
Boise State University
Principal Investigator
Alex Punnoose
Project type
Exploratory Research
Recently we have successfully developed Fe doped SnO2 which are ferromagnetic and semiconducting at room temperature. Our detailed structural and morphological studies using x-ray diffraction and…

XPS investigations of transition metal doped oxide semiconductors

Lead Institution
Boise State University
Principal Investigator
Alex Punnoose
Project type
Exploratory Research
In a recent paper, accepted for publication in Applied Physics Letters, we have shown that tin dioxide when doped with less than or equal to 1% cobalt produces room temperature ferromagnetism…
