Semiconductor Lasers: Device Physics and Applications
• Demonstration of an enhancement in the modulation bandwidth from 16 GHz to 28 GHz in an injection locked semiconductor laser with a coincident reduction in parasitic chirp. • Demonstration of room-temperature, continuous-wave operation of the first bipolar cascade laser. This laser demonstrated an internal efficiency of 150% and a measured external modulation efficiency of 99.3%. Continuous-w...
متن کاملReliability physics study for semiconductor-polymer device development
We discuss several aspects of the reliability physics of silicon–polyaniline heterojunctions, such as degradation effects induced by local heating, charge trapping and temperature changes. The results further confirm the quality of the devices electrical characteristics and their suitability for radiation and gas sensors applications. q 2003 Elsevier Science Ltd. All rights reserved.

Mathew C. Abraham, Professor Rajeev J. Ram There exists a substantial expertise in making extremely precise point-to-point current and potential difference measurements, however, at present there is no technique available to image the flow of currents in devices. Below we report on a preliminary investigation into using a magnetic force microscope (MFM) as a tool to render current contrast images.
