반도체 : 산소 분압에 따른 산화주석 박막의 전계효과 이동도 변화 분석
N+ 실리콘웨이퍼를 게이트전극으로 사용하여 bottom-gate 구조의 SnO2 TFT를 제조하였다. 게이트절연층으로 사용되는 SiO2/Al2O3막 위에 ～ 60 nm 두께의 SnO2막을 고주파 스퍼터링하여 박막트랜지스터의 활성층으로 사용하였다. SnO2막의 저항률을 높이기 위해 스퍼터링시 아르곤과 함께 산소를 주입하였다. 산소주입에 따른 박막트랜지스터의 이동도 변화를 조사하였으며, 그 결과를 SnO2막의 결정성, 산소결합상태, 광특성 측정 등을 통해 분석하였다. 결정성과 산소결합상태를 조사하기 위하여 XRD 및 XPS측정을 하였다. 산소주입에 따라 SnO2 TFT…
Адсорбційні властивості природних сорбентів щодо діоксиду сірки і парів води
Adsorption properties of natural sorbents (clinoptilolite, tripolies) with respect to water vapor and sulfur dioxide at the concentration of the latter of 200 mg/m 3 are compared. The protective time of the natural sorbents in regard to SO 2 is determined by their affinity to water molecules, phase ratio, and crystall…

Plasmonic Nanostructures for Enhanced Light-Matter Interactions: from Metal to Graphene
Plasmonics, a recent booming field, plays a major role in the fascinating research area of nanophotonics. Graphene, the newly rising star on the horizon of materials science and optoelectronics, exhibits exceptionally surprising properties. In optoelectronics, graphene (including other 2D materials) physics strongly o…
Hex-Tex: Laser Cutting Nonwoven Fabrics
Hex-Tex is a laser-cut nonwoven dress that explores the use of nonwovens in the apparel industry. Nonwoven fabrics eliminate the yarn stage in creating fabrics from fibers, thus it is an energy and cost efficient medium for apparel design.
LIMITED PROTEOLYSIS OF OAT 11S GLOBULIN BY PAPAIN
Limited proteolysis was found to occur during papain proteolysis of the oat 11S globulin. The initial limited proteolysis is extremely quick and consists of an N-terminal and C-terminal truncation of α-chains and C-terminal truncation of β-chains. Further on, the α-chain remnants are cleaved into similarly sized N-ter…
