Autor: Aazad Abbas, Imran Saleh, Graeme Hoit, Gurjovan Sahi, Sam Park, Jihad Abouali, Cari Whyne, Jay Toor

Publikováno v: Laparoscopic, Endoscopic and Robotic Surgery, Vol 6, Iss 3, Pp 97-102 (2023)

Objective: Smart insufflation (SI) techniques relying on valve and membrane-free insufflation are increasing in usage. Although considerable literature exists demonstrating the benefits of SI on procedural ease and patient outcomes, there remains a p

Engineering MoSe2/MoS2 heterojunction traps in 2D transistors for multilevel memory, multiscale display, and synaptic functions

Autor: Yeonsu Jeong, Han Joo Lee, Junkyu Park, Sol Lee, Hye-Jin Jin, Sam Park, Hyunmin Cho, Sungjae Hong, Taewook Kim, Kwanpyo Kim, Shinhyun Choi, Seongil Im

Publikováno v: npj 2D Materials and Applications, Vol 6, Iss 1, Pp 1-8 (2022)

Abstract We study a low voltage short pulse operating multilevel memory based on van der Waals heterostack (HS) n-MoSe2/n-MoS2 channel field-effect transistors (FETs). Our HS memory FET exploited the gate voltage (VGS)-induced trapping/de-trapping ph

Measuring the Bandgap of Ambipolar 2D Semiconductors using Multilayer Graphene Contact

Autor: Sam Park, Sungjae Hong, June Yeong Lim, Sanghyuck Yu, Jungcheol Kim, Hyeonsik Cheong, Seongil Im

Publikováno v: Small Science, Vol 3, Iss 2, Pp n/a-n/a (2023)

The bandgaps of monolayers and few layers in 2D semiconductors are usually measured by optical probing such as photoluminescence (PL). However, if their exfoliated thickness is as large as a few nanometers (multilayer over ≈5 L), PL measurements be

Photocatalytic Decolorization of Methylene Blue by N-doped TiO2 Nanoparticles Prepared Under Different Synthesis Parameters

Autor: Shimelis Kassahun, Zebene Kiflie, Dong Shin, Sam Park

Publikováno v: Journal of Water and Environmental Nanotechnology, Vol 2, Iss 3, Pp 136-144 (2017)

Although several studies concerning the preparation of nitrogen doped titanium dioxide visible-light active photocatalyst have already been reported, the effects of dopant concentration and calcination temperature have been rarely investigated. This
