In the title complex, [Ni(C(27)H(27)N(7))(C(3)H(7)NO)(H(2)O)](C(6)H(2)N(3)O(7))(2), the Ni(II) ion is coordinated in a slightly distorted octa-hedral coordination evironment by an NiN(4)O(2) ligand set. The tris-(N-methyl-benzimidazol-2-ylmeth-yl)amine ligand is in a tetra-dentate mode while a coordinated water molecu…
CdTe 및 Cu(In,Ga) $Se_2$ 박막 태양전지의 창층으로 널리 이용되는 CdS에서 Cd의 일부를 Zn으로 치환하면 두 물질 사이의 전자 친화력의 정합이 향상되고 에너지 밴드 갭이 증가하여 개방전압 및 광전류를 증가시킬 수 있다. 본 연구에서는 태양전지와 같은 광전소자에 적용되는 CdZnS와 CdTe로 구성되는 이종접합 소자를 제작하고 접합에서의 전류 전도기구를 조사하기 위해 온도에 따른 전류-전압 특성을 분석하였다. CdS/CdTe 접합의 전류 흐름은 계면 재결합과 터널링의 조합에 의해 조절되지만 CdZnS/CdTe 접합의 경우 상온 이상의 온도에서는 공…
The incorporation of extrinsic defects in semiconductors by ion implantation and \nappropriate annealing gives rise to instabilities that profoundly affect their \nelectronic and optical properties. Consequently, the knowledge of site location \nand hence the chemical nature of these defects is vital for the understan…

The application of law of the unity of opposite in Polymer Physics learning was introduced. Ten pairs of concepts concerning important questions in Polymer Physics, such as the definiteness of monomer structure and indefiniteness of chain and aggregation-structure, linear structure and cross-linking structure, absolut…
G. Cocco, E. Cadelano, and L. Colombo [Phys. Rev. B 81, 241412(R) (2010)] have suggested that combinations of shear and uniaxial strain can be used to open a band gap in graphene at much lower levels of strain than with the application of unaxial strain alone. They employed a unit cell of graphene in their studies and…
Microstructure and densification of Al-Ti-C-Cu system powder synthesis products made by laser sintering has been investigated. It was observed that in the combustion reaction, Al particles melt fist and then Cu reacts with Al to form Al2Cu phase, as a result, TiC grains precipitate out of the saturated liquid solution…

采用N，N-二甲基乙酰胺＋硫氰酸钾（KSCN）复合溶剂萃取分离苯-环己烷混合物，考察了复合溶剂中KSCN的质量分数、原料液组成、温度和复合溶剂与原料液的体积比（溶剂比）对苯的选择性系数（β）的影响。实验结果表明，在原料液组成一定时，卢随复合溶剂中KSCN含量的增加先增大后减小；当复合溶剂中KSCN含量一定时，卢随原料液中苯含量的增大而减小；在25—35℃，温度及溶剂比对β影响不大；在25℃、溶剂比为1．0、复合溶剂中KSCN质量分数为8％、原料液中苯体积分数不超过30％时，苯-环己烷混合物可达到较好的分离效果，β最大可达7．5。
Over the past decades, it has been well established that the mechanical behavior of materials changes when they are confined geometrically at least in one dimension to small scale. It is the aim of the 2010 Gordon Conference on 'Thin Film and Small Scale Mechanical Behavior' to discuss cutting-edge research on elastic…
