Journal ArticleDOI
Quantum confinement effect of silicon nanocrystals in situ grown in silicon nitride films
Tae Youb Kim,Nae-Man Park,Kyung-Hyun Kim,Gun Yong Sung,Young-Woo Ok,Tae Yeon Seong,Cheol Jong Choi +6 more
TL;DR: In this article, the size and structure of silicon nanocrystals were confirmed by high-resolution transmission electron microscopy and the photoluminescence peak energy as E(eV)=1.16+11.8∕d2 is evidence for the quantum confinement effect.
Journal ArticleDOI
High efficiency visible electroluminescence from silicon nanocrystals embedded in silicon nitride using a transparent doping layer
TL;DR: In this paper, a light-emitting diodes with a transparent doping layer on silicon nanocrystals (nc-Si) embeded in silicon nitride matrix formed by plasma-enhanced chemical vapor deposition was fabricated.
Journal ArticleDOI
Physics and Device Structures of Highly Efficient Silicon Quantum Dots Based Silicon Nitride Light-Emitting Diodes
TL;DR: An overview of the progress in the device physics and fabrications of the Si QD light-emitting diodes (LEDs) including new device structures to improve the light extraction efficiency as well as highlights in the growth of Si QDs and their quantum confinement effects (QCEs) is provided in this paper.
Journal ArticleDOI
Response to Cardiac Markers in Human Serum Analyzed by Guided-Mode Resonance Biosensor
Wan-Joong Kim,Bong Kyu Kim,Ansoon Kim,Chul Huh,Chil Seong Ah,Kyung-Hyun Kim,Jongcheol Hong,Seon Hee Park,Sanghoon Song,Junghan Song,Gun Yong Sung +10 more
TL;DR: The results show that the GMR biosensor will be very useful in developing low-cost portable biosensors that can screen for cardiac diseases.
Journal ArticleDOI
Enhancement in light emission efficiency of a silicon nanocrystal light-emitting diode by multiple-luminescent structures.
TL;DR: In this paper, the size of Si nanocrystals (nc-Si) is smaller than the free exciton Bohr radius of bulk Si ( ∼ 4.6 nm), the light emission effiency could be much enhanced due to an increase in overlapping of electron-hole wave functions, that is, a quantum confi nement effect.
