  • This study demonstrates a different approach method to fabricate antimony selenide (Sb2Se3) thin-films for the solar cell applications. As-deposited Sb2Se3 thin-films are fabricated via electrodeposition route and, subsequently, annealed in the temperature range of 230 ~ 310℃. Cyclic voltammetry is performed to investigate the electrochemical behavior of the Sb and Se ions. The deposition potential of the Sb2Se3 thin films is determined to be -0.6 V vs. Ag/AgCl (in 1 M KCl), where the stoichiometric composition of Sb2Se3 appeared. It is found that the crystal orientations of Sb2Se3 thin-films are largely dependent on the annealing temperature. At an annealing temperature of 250 ℃, the Sb2Se3 thin-film grew most along the c-axis [(211) and/or (221)] direction, which resulted in the smooth movement of carriers, thereby increasing the carrier collection probability. Therefore, the solar cell using Sb2Se3 thin-film annealed at 250 ℃ exhibited significant enhancement in JSC of 10.03 mA/cm2 and a highest conversion efficiency of 0.821 % because of the preferred orientation of the Sb2Se3 thin film.

  • InSb temperature dependent hall effect of multilayerd structures were investigated. According to variation of magnetic field measured hall coefficient, Hall mobility, carrier density and hall voltage. For the measurement of electrical properties of hall device, evaperated InSb thin film fabricated with series and parallel multilayers. We found that the XRD analysis of InSb thin film showed good properties at 200$^{\circ}C$, 60 minutes. Resistance of ohmic contact increased linearly due to increasing current. Some of device fabrication technique and analysis of Hall effect were discussed.

  • The germanium films were deposited by metal organic chemical vapor deposition using $Ge(allyl)_4$ precursors on TiAlN substrates. Deposition of germanium films was only possible with a presence of $Sb(iPr)_3$, which means that $Sb(iPr)_3$ takes a catalytic role by a thermal decomposition of $Sb(iPr)_3$ for Ge film deposition. Also, as Sb bubbler temperature increases, deposition rate of the Ge films increases at a substrate temperature of $370^{\circ}C$. The GeTe thin films were fabricated by MOCVD with $Te(tBu)_2$ on Ge thin film. The GeTe films were grown by the tellurium deposition at $230-250^{\circ}C$ on Ge films deposited on TiAlN electrode in the presence of Sb at $370^{\circ}C$. The GeTe film growth on Ge films depends on the both the tellurium deposition temperature and deposition time. Also, using $Sb(iPr)_3$ precursor, GeSbTe films with hexagonal structures were fabricated on GeTe thin films. GeSbTe films were deposited in trench structure with 200 nm*120 nm small size.

  • ATO(antimony-doped tin oxide) 투명전도막을 sol-gel dip coating 방법에 의해 $SiO_2$/glass 기판 위에 성공적으로 제조하였다 ATO막의 결정상은 $SnO_2$상임을 확인하였고, 막의 두께는 withdrawal speed를 50 mm/minute로 코팅시 약 100 nm/layer였다. $SiO_2$/glass 기판 위에 코팅한 400 nm두께의 ATO 박막을 질소분위기에서 annealing한 후, 측정한 광 투과율과 전기 저항치는 각각 84%와 $5.0\times 10^{-3}\Omega \textrm{cm}$였다. 이러한 특성은 $SiO_2$막이 Na 이온의 확산을 제어하여 $Na_2SnO_3$ 및 SnO와 같은 불순물의 형성을 억제하고, 막 내부의 Sb의 농도와 $Sb^{3+}$에 대한 $Sb^{5+}$의 비를 증가시키는데 기여했기 때문으로 확인되었다. 또한, $N_2$ annealing은 $Sb^{5+}$뿐만 아니라 $Sn^{4+}$를 환원시킴으로써 전기전도도를 향상시킴을 확인하였다.

  • In this research, properties of $N_2$-doped $Sb_2Te_3$ thin film were evaluated using 4-point probe, XRD and AFM. $Sb_2Te_3$ material has faster crystallization rate than $Ge_2Sb_2Te_5$, but sheet resistance difference between amorphous and crystallization state is very low. This low sheet resistance difference decreases sensing margin in reading operation at PRAM device operation. Therefore, in order to overcome this weak point, $N_2$ gas was doped on $Sb_2Te_3$ thin film. Sheet resistance difference between amorphous and crystallized state of $N_2$-doped $Sb_2Te_3$ thin film showed about $10^4$ times higher than Un-doped $Sb_2Te_3$ thin film because of the grain boundary scattering.

  • In this study, Bi-Sb thin film structure was prepared by thermal evaporation method. The electrical, optical transmission and structural characteristics of the prepared samples were introduced before and after thermal annealing process. At temperature of $500^{\circ}C$, the absorption of the structure was improved to reach 97% at near-infrared region. As well, the thermal annealing caused to reduce the bulk resistance of the Bi-Sb thin film structure. The morphology of Bi-Sb structure was also improved by thermal annealing as characteristic islands of the structure appear clearly in form hexagonal areas distinct from each other. This study is aiming to examine such structures if they are employed as photonic devices such as photodetectors, LED's and optical switches.
