| description |
This study is conducted to develop computer-based measurement system to obtain energy band gap of semiconductor diode. The forward voltage technique is a common technique used to determine energy band gap of diode driven by constant current source. The system is developed to adapt and implement an equation of energy band gap deduced from previous research using computer-based measurement in order to produce more accurate and reliable result of energy band gap. The system is consisted of personal computer, interface board, sensors and circuit. The graphical user interface (GUI) of the system is developed using LabVIEW from National Instruments. The developed system is tested on silicon and germanium diode and four types light-emitting diode (LED) which are red, orange, blue and green. Their temperature-forward voltage characteristics (T versus VF) under 12mA constant current source are measured to calculate energy band gap and wavelength of emitted photon. Measurement was carried from 5C to 95C with temperature intervals of 5C. Result shows that the system successfully measured energy band gap of all tested diode. The band gaps of silicon diode 1N4007 and germanium diode 1N34 were determined to be 1.99 0.05 eV and 0.88 0.03 eV respectively. The band gaps of orange, red, blue and green LEDs were obtained to be 1.82 0.03 eV, 1.98 0.02 eV, 3.90 0.03 eV and 2.58 0.05 eV. This study implies that this computer-based measurement system has improved and simplifies the experiment set-up and process to obtain the energy band gap as reported in previous studies. |
