Description of Research

Dr. Tokranova's research interests focus on Micro-Electro-Mechanical Systems (MEMS) and nanosystems. Her current research projects are multidisciplinary and lie at the intersection of semiconductor materials and device physics, materials sciences, optics and biochemistry. They encompass two major research directions. 

The first is the design and fabrication of MEMS sensor and actuators, including pressure sensors and optical gratings, for various kinds of applications.

The second research focus is on nanoscale silicon structures, which are produced using electrochemical etching. Silicon with pore sizes from 1nm can be used for a wide variety of applications including photonics (e.g., photonic bandgap structures), photovoltaics (e.g., hybrid solar cells).
