Research Interest: Currently my group is involved in several projects in photonics and spintronics/magnetics along with a highly focused effort on oxide Molecular Beam Epitaxy (MBE) system for epitaxial growth of multi-ferroic oxides on semiconductor substrates. Main research areas are:

 

1)    Noise Measurements: We measure low-frequency (1/f) noise in various electronic and photonics devices for understanding fundamental processes giving rise to low-frequency flicker noise in these devices. Noise is an important parameter for sensors and detectors. It is also an important diagnostic tool for measuring reliability of electronic and photonic devices. Our focus is to develop accurate measurement techniques and models to understand low frequency noise in electronic and optoelectronic devices.

2)    Fabrication of High Performance HOT HgCdTe Avalanche Photodiodes (APD): MWIR APDs are being designed, MBE grown , fabricated, and characterized in collaboration with EPIR Technologies, Inc. The aim is to develop MWIR thermoelectrically cooled HgCdTe APDs on Silicon substrates. We are currently in the phase II of a STTR grant from Air Force Office of Scientific Research. Our group is developing novel fabrication techniques to enhance the performance of hetero-integrated APDs and we have set up a state of the art noise, gain and excess noise measurement system for UV and IR APDs. We are developing a heterodyned fiber laser for high frequency IR APD measurement.

3)    Multifunctional Conducting Oxides for Space Applications: The objective of this research effort is to develop affordable, reliable and reproducible technique to deposit large are, uniform ZnO-based transparent conductive oxide film with high transmissivity in visible band to offer a discharge channel. We are currently in Phase II of this STTR program from NASA.

4)    MBE Growth of Multiferroic Oxides: Multiferroic oxide thin films are being grown on semiconductor substrates. The aim is to integrate the oxide thin films with the semiconductor substrates and be able to make them interact for advanced microwave applications.  Our group is developing novel in situ real time surface characterization techniques for feedback control of surface stoichiometry during epitaxial growth.

 

UIC Molecular Beam Epitaxy Lab: The RF Plasma assisted MBE system is located in the Research Resources Center – East at UIC. The MBE system is exclusively used by  our group for epitaxial growth of multiferroic thin film heterostructures.  The Oxide MBE system is equipped with a modified high pressure RHEED system and a retractable quartz crystal monitor (QCM) on a bellow for accurate flux and growth rate monitoring. An in-situ Total Reflection Angle X-Ray (TRAX) system is being developed for accurate surface stoichiometry measurements during growth.

 

Education and Outreach:  Our group actively participates in the NSF funded REU and RET sites at the University of Illinois at Chicago. Each summer a RET fellow and a REU student is hosted in our lab. Senior graduate students and post doctoral researchers mentor the RET fellows and REU students in the labs.
