Chemical bath deposition(C.B.D.)방법으로 다결정 $Cd_{1-x}Zn_{x}S$ 박막을 스라이드 유리(coming-2948) 기판위에 성장시켜 열처리하고 X-선 회절무늬를 측정하여 결정구조를 밝혔다. $550^{\circ}C$로 $N_{2}$ 속에서 열처리한 시료의 X-선 회절무늬로부터 외삽법으로 구한 격자상수는 CdS인 경우 $a_{0}\;=\;4.1364{\AA}$, $c_{0}\;=\;6.7129{\AA}$였으며 ZnS인 경우는 $a_{0}\;=\;3.8062{\AA}$, $c_{0}\;=\;6.2681{\AA}$였다. Van der Pauw 방법으로 Hall 효과를 측정하여 운반자 농도와 이동도의 온도 의존성을 연구하였다. 광전도 셀의 특성으로 스펙트럼응답 감도, 최대허용소비전력 및 응답시간을 측정하였다. Polycrystalline $Cd_{1-x}Zn_{x}S$ thin film were grown on slide glass(corning-2948) substrate using a chemical bath deposition (C.B.D) method. They were annealed at various temperature and X -ray diffraction patterns were measured by X-ray diffractometor in order to study $Cd_{1-x}Zn_{x}S$ polycrystal structure using extrapolation method of X-ray diffraction patterns for the CdS, ZnS sample annealed in $N_{2}$ gas at $550^{\circ}C$. It was found hexagonal structure which had the lattice constant $a_{0}\;=\;4.1364{\AA}$, $c_{0}\;=\;6.7129{\AA}$ in CdS and $a_{0}\;=\;3.8062{\AA}$, $c_{0}\;=\;6.2681{\AA}$ in ZnS, respectively. Hall effect on these sample was measured by Van der Pauw method and then studied on carrier density and mobility depending on temperature. We measured also spectral response, sensitivity maximum allowable power dissipation and response time on these sample.

[ $CuInTe_2$ ] 다결정은 수평전기로에서 합성하고, $CuInTe_2$ 단결정은 수직 Bridgman 방법으로 성장시켰다. $CuInTe_2$ 단결정의 c축에 수직 및 평행한 시료의 광전도도와 광발광특성을 293K에서 20 K의 온도영역에서 측정하였다. 측정된 광전류 봉우리로부터 구한 c축에 수직 및 평행한 시료의 에너지 띠 간격은 상온에서 각각 0.948 eV와 0.952 eV였다. 광전류 봉우리와 광발광 봉우리의 에너지차는 포논에너지이며 상온에서 c축에 수직 및 평행한 시료의 에너지차는 각각 22.12 meV와 21.4 meV였다. 또한 광전류 스펙트럼으로부터 시료의 spin-orbit 상호작용과 결정장 상호작용에 의한 가전자대의 갈라짐 ${\Delta}cr$과 ${\Delta}so$는 각각 0.046, 0.014 eV였다. [ $CuInTe_2$ ] synthesised in a horizontal electric furnace was found to be polycrystalline. Single crystals of $CuInTe_2$ were grown with the vertical Bridgman technique. The photoconductivity and photoluminescence of the crystals were measured in the temperature range 20 to 293 K. From the photocurrent peaks measured for the samples both perpendicular and parallel to c-axis, the energy band gaps of the samples were found to be 0.948 eV and 0.952 eV at room temperature respectively. The energy difference of the photocurrent and photoluminescence peaks of the samples both perpendicular and parallel to the c-axis measured at room temperature was a phonon energy, and its values were 22.12 meV and 21.4 meV respectively. The splitting of the valence band due to spin-orbit and crystal field interaction was calculated from the photocurrent spectra of the samples, The ${\Delta}cr\;and\;{\Delta}so$ are 0.046,0.014 eV respectively.

Mobile harbor system is a new concept of the system for harbor loading and unloading operation at open sea. This new concept is being developed as an alternative plan for harbor loading and unloading operations instead of expanding capacity of existing quay or new construction of quay. Lack of proper coastal lines for building new quays and increasing environmental concerns justify the open sea loading and unloading of containers to and from containerships. Current approaches, which are still in the stages of idea conception, are divided in two directions. The first is the idea of building a unified vessel that has cranes and container barge in a single unit. The second idea is separating crane vessel and container transport vessel as separate modules, thus called as modular mobile harbor system. This paper describes the issues related to the container transport vessel, which we call shuttle module, that is designed for receiving containers from the crane module, transporting container to the quay, and unloading at the quay. The reverse operations are considered in the design of the shuttle module as well. Important issues related to the design of shuttle module are discussed and initial concept design is proposed in the paper.
