AbstractGaN is an attractive wide bandgap semiconductor material for optoelectronic device applications at blue and UV wavelengths. The breakdown behavior of interdigital MSM type of AlGaN UV photodetectors (PDs) are reported here. The A1GaN was deposited using MOCVD technique. The MSM devices were fabricated using undoped AlGaN (Al composition is 0.13) epitaxial layer on sapphire substrate. Au/Ti metallization was patterned as metal electrodes on AlGaN. Very high UV responsivity of the devices was achieved at DC bias voltage in the range of 60–140V depending on the device dimensions. The breakdown voltage exhibits a negative temperature coefficient. The relationship between the breakdown voltage and device dimensions has been investigated using both of I-V, C-V characteristics. It has been found that annealing of the contact modifies the device characteristics, in particular, the breakdown behaviors.

Nanoscale tellurium (Te) materials are promising for advanced optoelectronics owing to their outstanding photoelectrical properties. In this work, high-performance optoelectronic nanodevice based on a single tellurium nanotube (NT) was prepared by focused ion beam (FIB)-assisted technique. The individual Te NT photodetector demonstrates a high photoresponsivity of 1.65 × 104 AW−1 and a high photoconductivity gain of 5.0 × 106%, which shows great promise for further optoelectronic device applications.

Interest in II-VI semiconductors centres around optoelectronic device applications. The wide band gap II-VI semiconductors such as ZnS, ZnSe and ZnTe have been used in lasers and electroluminescent displays yielding room temperature blue luminescence. The narrow gap II-VI semiconductors such as CdTe and HgxCd1-x Te are currently used for infrared detectors, where the band gap can be varied continuously by changing the alloy composition x.Two major sources of precipitation can be identified in II-VI materials; (i) dopant introduction leading to local variations in concentration and subsequent precipitation and (ii) Te precipitation in ZnTe, CdTe and HgCdTe due to native point defects which arise from problems associated with stoichiometry control during crystal growth. Precipitation is observed in both bulk crystal growth and epitaxial growth and is frequently associated with segregation and precipitation at dislocations and grain boundaries. Precipitation has been observed using transmission electron microscopy (TEM) which is sensitive to local strain fields around inclusions.
