Morehead RF Micro Characterization Lab

 

The RF/micro characterization lab at the Morehead State University Space Science Center is developed to meet the needs of measurement and characterization from DC up to 40 GHz on electronic and MEMS devices as well as their related materials. Meanwhile, the lab serves as an instructional role to nurture students experimental skills and promote efficient teaching and learning in various existing courses. The instruments in this lab are deliberately acquired to provide the complete capability for conducting the reliability testing on RF MEMS switches; the device characterization on diodes, transistors and solar cells; and the non-destructive I-V and C-V measurements on dielectric and high-k metal oxide films. The entire lab room can be switched to the yellow light condition for performing photolithographic processes. 

Currently active projects include:

1. p-type ohmic contact for heterojunction bipolar transistors

This research is to develop an optimized ohmic contact on a thin p-type base of AlGaAs/GaAs and InGaP/GaAs heterojunction bipolar transistors (HBTs).

2. Reliability of RF MEMS switches

Various novel contact structures are being investigated for more reliable MEMS switches. A second mechanical spring approach is also being evaluated in improving the reliability of MEMS switches.

3. Photovoltaic decay of thin-film CdTe solar cells

This is an on-going research on the photovoltaic decay behavior of CdTe/CdS thin-film solar cells. The goal is to improve the fundamental understanding of CdTe devices and thus lead to even further advances in cost per watt for CdTe/CdS thin-film solar cells.

4. High-dielectric constant metal oxide materials

This research project is to develop high-dielectric constant metal oxide materials as replacements for the conventional gate oxide, SiO2, used in MOSFET technology.

 

The RF/micro characterization lab is still under construction, and lab activities are being developed. The following existing courses use this lab: 

ITEC 242 Communications Electronic Circuits

ITEC 342 Electronic Devices and Circuits

ITEC 445 Computer electronics
