The growth was performed using TMIn  TMGa  AsH3  and PH3 as growth precursors in a horizontal reactor. The substrates on a graphite susceptor were heated by inductively coupling RF power  their temperatures were detected by a thermocouple  and the reactor pressure was kept at 10000 Pa. The growth structure of detector included In0.82Ga0.18As buffer with the thickness of 100 nm  In0.82Ga0.18As absorption layer with the thickness of 2.8 m  and the InP cap with the thickness of 0.8 m. The planar type of p-i-n detector was fabricated by Zn diffusion. The properties of In0.82Ga0.18As detector were studied  the curves of the I-V characteristics  the range of response spectrum  and the detectivity (D*) were obtained.

The influences of spectrum reconstruction caused by the diffraction and extended light source in Fourier Transform Infrared Spectrometer (FTIR) are analyzed. A method to reduce the noises in spectrum reconstruction and the relationship between coherent intensity and solid angle of light source are discussed. An extended light source with suitable size is chosen  considering the requirement of SNR and spectrum resolving power in the optical design. Furthermore  the fabrication of micro multi-step mirrors  which is the core part of FTS  is investigated. Three methods for fabricating multi-step micro mirrors are demonstrated. 2011 IEEE.   Cosmic-ray energy spectrum around the knee obtained by the Tibet experiment and future prospects 期刊论文  OAI收割 ADVANCES IN SPACE RESEARCH, 2011, 卷号: 47, 期号: 4, 页码: 629-639 作者:  Tibet ASGamma Collaboration 收藏  |  浏览/下载：15/0  |  提交时间：2015/12/02 AIR-SHOWER ARRAY  PRIMARY PROTON SPECTRUM  SHOCK ACCELERATION  GAMMA-RAYS  TEV  RANGE   Broadband tunable external cavity laser using a bent-waveguide quantum-dot superluminescent diode as gain device 期刊论文  OAI收割 chinese physics b, 2011, 卷号: 20, 期号: 6, 页码: art. no. 064202 作者:  Jin P 收藏  |  浏览/下载：52/4  |  提交时间：2011/07/15 LIGHT-EMITTING-DIODES  OPTICAL-PROPERTIES  TUNING RANGE  NM  EMISSION  SPECTRUM  SPECTROSCOPY   Broadband external cavity tunable quantum dot lasers with low injection current density 期刊论文  OAI收割 optics express, 2010, 卷号: 18, 期号: 9, 页码: 8916-8922 作者:  Wang WY;  Jin P 收藏  |  浏览/下载：181/44  |  提交时间：2010/05/24 LIGHT-EMITTING-DIODES  NM TUNING RANGE  SUPERLUMINESCENT DIODES  WELL LASER  EMISSION  SPECTROSCOPY  SPECTRUM
