abstract:Because the short wavelength optical read-write system has the advantage of increasing the storage capacity of optical disk, hence, it is the trend for related products to head toward shorter wavelength in recent years; moreover, because ZnSe has direct energy band gap of 2.69eV, it is thus of high potential to be used as blue ray device. Although in the development of blue laser and light emitting diode, devices in GaN series have played a leading role, yet in the short wavelength detection device aspect, devices of ZnSe series are still very promising; since many counties have research results in this field. Hence, our lab has devoted to the R&D of optoelectronic sensor device of ZnSe series in recent years. In the previous years, under the support of the budge from National Science Council and the efforts of our lab, we have completed the preparation and test of short wavelength optoelectronic devices, namely, ZnSe/Si schottky photodiode, ZnSe/Si PIN photodiode, ZnSe/Si HBT, n-ZnSe/p-Si/n-Si Heterojunction phototransistors, ZnSe/Si MSM-PD, n-ZnSe/p-GaAs/n-GaAs HBT; in recent years. This lab also successfully developed integrated short wavelength optical detection chip that associates two devices of ZnSe MSM-PD and InGaP/GaAs HBT; in this project, it is hoped that, through process improvement on individual device, the optoelectronic characteristics of the integrated device is optimized, and the efficiency and application field of the short wavelength optical detector can then be enhanced. In this project, characteristic improvement is going to be targeted respectively at two devices of ZnSe MSM-PD and InGaP/GaAs HBT, after it is completed, integration will be done further; accompanied with optoelectronic characteristic measurement and analysis and comparison, short wavelength optical detection ship can be developed with good characteristics such as: high sensitivity, high response speed, multiple function layers, low power consumption and low noise. The development of such technology can also be helpful to the preparation of future advanced short wavelength optoelectronic integrated circuit (OEIC) device. Furthermore, it is also helpful to the development of short wavelength optical detection device that is practical in many application fields and is of high quality and high sensitivity.
