Details of research work carried out
As for research, Professor Lin efforts focus on mechanical engineering, coating technology, mechatronic, nanotechnology(esp. in diamond coating technology), just like diamond films, DLC, CNTs, nano-diamond films, ultra-nano-diamond films, untra-nano-diamond wire(rods) etc.. Professor Lin established Diamond Group and Thin Film Lab. Many novel and high practicality studies are proceeding, such as novel hard coating technique, nano material applications in opto-electro-mechanical, fuel cell, various optical thin films design, nano diamond thin film, Carbon nanotubes, light reflection thin film, novel coating technology on plastic, and so on.
There are many homemade and advanced instruments on Thin Film Lab. Such as MPCVD, MPJCVD, RF-sputter, ion implanter, fuel cell, fuel cell test station, thin film adhesion test machines etc..
Professor Lin has abundant experiences in cooperation with industrial companies, and many qualified papers have been published in the international journal. The following describes some of the study objectives:
(i) On Surface Plasmon Resonance:
Although metal doping in diamond like carbon (DLC) films prepared by chemical/physical vapour deposition techniques had been the issue of obtaining a new class of materials in nineties, but the difficulty of dispersing the metal particles homogeneously in the DLC matrix by the techniques used by the researchers was found to be difficult. The metal particles were found to form clusters in the DLC matrix and formed carbide clusters in case of carbide forming metals. Major effort was directed towards reducing the residual stress in the DLC coating. But, DLC films being a large band gap material, metal inclusion in nano-crystalline form should also reveal interesting optical properties like surface plasmon resonance in these classes of composite materials.
Studies on the optical properties of composite materials composed of ultra-fine metal particles (Ag, Cu etc) having different grain sizes as well as inter-grain distances embedded in diamond like carbon (DLC) matrix were carried out. The composite films were prepared by simple RF Sputtering and Microwave Plasma Jet Vapor Deposition technique which are a cheap and scalable technique besides being capable of depositing films on irregular surfaces. Optical absorption studies in these materials having technological applications were critically studied.
(ii) Programme on CNTs based sensor device:
Development of sensors for detecting various chemical species and gases in many industrial, medical, environmental pollution control and commercial applications is in great need. Metal oxide gas sensors have been the subjects of large number of investigations during the past. Most of the sensors based on oxide materials showed better and acceptable sensing behaviour at significantly higher temperatures. The growing need for the development of room temperature sensors to be used in explosive ambience, and development of sensing materials which would be able to detect gases.
In this regard, carbon nanotubes (CNTs) is emerging as a promising candidate since the surface area of the CNTs is very large and there are indications that electrical properties might change at room temperature. Due to their fascinating physical and chemical properties, CNTs have emerged as ideal candidates for nanoscale devices. A number of techniques are available to synthesis carbon nanotube, most common of which are arc discharge, laser ablation and Chemical Vapour deposition processes. But all these synthesis techniques inherently produce carbon nanotubes along with various impurities in the form of amorphous carbon, metal catalysts and many carbonaceous particles etc. It needed further purification to produce high quality CNTs for device applications. So the challenge still lies on the large-scale synthesis of CNTs directly onto the wafer/substrate in their purest form and in a very cost-effective way. This has ushered a new hope to develop room temperature sensors for methane detection based on CNTs.
This research has been directed towards the synthesis and characterization of Carbon nanotubes and nanodiamond rod by adopting cost-effective and scalable vapour deposition technique for methane gas sensor applications. The films were deposited onto silicon and SnO2 –coated glass substrates. The films were characterized (TEM, SEM, EDAX, Raman Spectroscopy, FTIR, Glancing angle X-ray, AFM etc.) to understand the growth process so that films having higher sensitivity for gas detection could be obtained. Efficiency of retrieving the chemically active surface are still being studied critically.
During the course of synthesizing the films and characterizing them, Professor Lin utilized several techniques for charaterization like XRD, UV-VIS-NIR spectrophotometer, SEM, TEM, AFM, EDS, PL, Raman measurements, I-V and C-V measurement, ac and dc conductivity, FTIR etc quite extensively.
(iii) Breakthrough the barrier of intelligent CVD System also be the target of Professor Lin’s research, and how to use the mathematical calculation method to solve this issues were development.
(iv) More than 30 projects were performed by Professor Lin during the decade late. These projects came from the National Science Council, Ministry of Education, Ministry of Industry, business, and so on. Professor Lin also transferred the RF PVD target novel technology to Ritec. Co. etc..
