Zinc oxide, ZnO are semiconductor in group II-IV and are really popular nowadays due to high direct bandgap (3.37eV), low toxicity, can withstand high temperature, large exciting binding energy (60meV) and many types of structural properties. Recently, there are many researchers used ZnO nanostructure to invent many sensors such as humidity sensor and gas sensor due to its high sensitivity towards environment. There are a lot of techniques to fabricate the Zno nanostructure. For instance, Pulsed Layer Deposition (PLD), Chemical Vapour Deposition (CVD), Hydrothermal, Sputtering and Sol-Gel. But, among all the technique, hydrothermal technique are the most common techniques used due to simple and produce high quality of ZnO thin films with very low cost, low temperature and low time consumption. In this project, the ZnO thin film were deposited on glass substrate using hydrothermal technique with gold that act as catalyst in a temperature of between 50°C until 90°C. Other aspect also being observed in this project such as time taken for fabrication and the thickness of gold catalyst and the results are reported in this thesis. X-Ray Diffraction (XRD) is used to determine the purity of the ZnO nanostructure by observing the presence of ZnO layer with high peak of crystal orientation and used of Energy-Dispersive X-Ray Spectroscopy (EDX) for recording the element composition. Furthermore, the used of Field Emission Scanning Electron Microscopy (FESEM) for the study of ZnO morphology or shape and Surface Profiler to determine the thickness of ZnO nanowire on the glass substrate. The glass substrate that contain ZnO nanowire then load into PCB and mounted with silver electrode. The used of 2-probe method for the determination of electrical properties of ZnO nanowire on the glass substrate. The main focus is the resistance and resistivity of the ZnO nanowire under the different temperature. The experimental shows positive result as the resistance are linearly to the temperature. The resistance will decrease as the temperature increase with the range of 120ºC to 300°C.
Report on Ethics Seminar
Title: Challenges of Employment in Engineering
Speaker: Ir Juraimi Masood
On 16th April 2019, all 4th year student from faculty of Electrical Engineering are attending the talk about the challenges of employment n engineering. This talk was held in School of Electrical Engineering (SEE) at P19 DK6. The program duration is about 2 hour and 30 minutes which start at 2.30 pm and end at 5.00 pm. This seminar are compulsory for every SEE student that take subject Engineering Ethics (SKEE 4012).
Starting of the talk, Ir Juraimi give some brief about his background. In 1974, Ir Juraimi study at SKLKTP Pasir Raja while his secondary school is at SDAK Seremban. In 1989, he manage to further his study in diploma at Universiti Teknologi Malaysia (UTM) Kuala Lumpur (UTMKL) in course of Electrical Communication. After completing the diploma period, he finally graduated from UTMKL with flying colors.
His first job was at Telecom Training Centre for one and half year. On 1986 until 199, he worked at MSE PG as a management trainer. MSE PG is a company that focus on ship building and repair. As management trainer, he acts as ship repair estimator. 0n 1992 until 1996, Ir Juraimi change his workplace to SIME in Sembarang.
This company more towards heavy engineering. His job is to design, make a project plan and project cost for a construction, quality and safety. In 1996 until 1997, he moved to Kuala Lumpur as there were in develop state. He worked at KTA Tenaga which provide the air conditioner plant in KLCC. He works as a resident engineer and also a consultant. From 1998 until now, he works at Berth Construction at Tanjung Pelepas.
After that, he shares about his work life and the challenging face by him. He said when we working with different boss, our working type need to change according to the boss style. If not, we are going to have problem when him. From his experience, he said many challenge when working with many different type of boss.
