Zinc oxide (ZnO) is a strong luminescent material, as are several polymers. These two materials have distinct drawbacks and advantages, and they can be combined to form nanostructures with many important applications, e.g., large-area white lighting. This paper discusses the origin of visible emission centers in ZnO nanorods grown with different approaches.(More)
Low-dimensional InN/InGaN quantum dots (QDs) are demonstrated for realizing highly sensitive and efficient potentiometric biosensors owing to their unique electronic properties. The InN QDs are biochemically functionalized. The fabricated biosensor exhibits high sensitivity of 97 mV/decade with fast output response within two seconds for the detection of(More)
Trapping in microwave devices affects the time domain and frequency domain behaviour. In the time domain, surface traps result in the well known gate lag effect. A model, developed to predict these effects in HEMT devices, is used to simulate frequency domain behaviour of trapping in HEMT device. Trapping is known to cause distortion in intermodulation(More)
