The objective of this study is to characterize and analyse defects in solar cell devices. Materials used to fabricate solar cells are not defects free and therefore, there is a need to investigate defects in cells. To investigate this, a topographical technique was developed and employed which uses a non-destructive methodology to analyse solar cells. A system was built which uses a technique based on a laser beam induced current (LBIC). LBIC technique involves focusing light on to a surface of a solar cell device in order to create a photo-generated current that can be measured in the externa

In choosing a passivant of power thyristors and diodes, there are two important considerations in addition to the usual requirement for providing uniform high breakdown voltage via substrate.

Excessive fluid-borne noise in hydraulic systems is a problem the fluid power industry has long struggled to address. Traditional noise control devices such as Helmholtz resonators, tuning coils, and Herschel-Quincke tubes are generally too large for fluid power systems unless the speed of sound in the device can be reduced. A compliant lining can achieve this effect, but compliance (and lossy compliance) has had little attention in noise control in general, and in fluid power in particular. One means to achieve compliance in these devices, especially at elevated pressures, is through a liner

Abstract:
abstract: This PhD thesis consists of three main themes. The first part focusses on modeling of Silver (Ag)-Chalcogenide glass based resistive memory devices known as the Programmable Metallization Cell (PMC). The proposed models are examined with the Technology Computer Aided Design (TCAD) simulations. In order to find a relationship between electrochemistry and carrier-trap statistics in chalcogenide glass films, an analytical mapping for electron trapping is derived. Then, a physical-based model is proposed in order to explain the dynamic behavior of the photodoping mechanism in lateral PMC

碩士<br>國立中央大學<br>機械工程學系<br>105<br>Thermal interface materials (TIMs) is a key component in the majority of power electronic systems. Heat, generated by the semiconductors, has to be transferred to a heat sink and finally dissipated to ambient. In this work, we report a versatile and solvent-free method for the particle size reduced of exfoliated graphite nanoplatelets (EGN) into high-quality ball-milled exfoliated graphite nanoplatelets (BMEGN) by simple solid-state ball-milling, fillers are embedded and thermally cured with Polydimethylsiloxane (PDMS) to make a highly stretchable BMEGN-embedde

Abstract:
碩士<br>國立中央大學<br>機械工程學系<br>103<br>In this study, the thermal management of the Converter system is of great importance since very high voltage/current will be switched intermittently and/or continuously and high temperature is detrimental to the service life of electronics, especially for the switching devices such as insulated gate bipolar transistor (IGBT). Thermal interface materials (TIMs) are generally composed of highly conductive particle fillers such as high thermal conductivity of graphite and a matrix such that efficient heat transfer and good compliance of the interface material can
