Autor: Won‐Yong Lee, Min‐Sung Kang, Jae Won Choi, Si‐Hoo Kim, No‐Won Park, Gil‐Sung Kim, Yun‐Ho Kim, Sang‐Kwon Lee

Publikováno v: Advanced Electronic Materials, Vol 9, Iss 8, Pp n/a-n/a (2023)

Abstract 2D transition‐metal dichalcogenide (TMDC) materials are promising candidates with excellent thermoelectric (TE) properties owing to their low dimensionality in electronic and phonon transport. However, the considerable coupling of the Seeb

Abnormal Seebeck Effect in Vertically Stacked 2D/2D PtSe2/PtSe2 Homostructure

Autor: Won‐Yong Lee, Min‐Sung Kang, Jae Won Choi, Si‐Hoo Kim, No‐Won Park, Gil‐Sung Kim, Yun‐Ho Kim, Eiji Saitoh, Young‐Gui Yoon, Sang‐Kwon Lee

Publikováno v: Advanced Science, Vol 9, Iss 36, Pp n/a-n/a (2022)

Abstract When a thermoelectric (TE) material is deposited with a secondary TE material, the total Seebeck coefficient of the stacked layer is generally represented by a parallel conductor model. Accordingly, when TE material layers of the same thickn

Multi-Layer SnSe Nanoflake Field-Effect Transistors with Low-Resistance Au Ohmic Contacts

Autor: Sang-Hyeok Cho, Kwanghee Cho, No-Won Park, Soonyong Park, Jung-Hyuk Koh, Sang-Kwon Lee

Publikováno v: Nanoscale Research Letters, Vol 12, Iss 1, Pp 1-6 (2017)

Abstract We report p-type tin monoselenide (SnSe) single crystals, grown in double-sealed quartz ampoules using a modified Bridgman technique at 920 °C. X-ray powder diffraction (XRD) and energy dispersive X-ray spectroscopy (EDX) measurements clear

Thermoelectric characterization and fabrication of nanostructured p-type Bi0.5Sb1.5Te3 and n-type Bi2Te3 thin film thermoelectric energy generator with an in-plane planar structure

Autor: No-Won Park, Tae-Hyun Park, Jay-Young Ahn, So-Hyeon Kang, Won-Yong Lee, Young-Gui Yoon, Soon-Gil Yoon, Sang-Kwon Lee

Publikováno v: AIP Advances, Vol 6, Iss 6, Pp 065123-065123-10 (2016)

This paper presents in-plane bismuth-telluride-based thermoelectric (TE) energy generators fabricated using metal-shadow and radio-frequency sputtering methods at room temperature. The TE energy generators consist of four couples of 300-nm-thick nano
