Investigation of Metal Nano Layer Formation by the Tunneling Current through the Thin Oxide Film in the Electrolyte–Oxide–Silicon System

Lee S-H., Cheon J-H, Choi S., Choi Y., Choi S., Choi Y., Park Y.J., Seoul National University, KR

In the researches on Electrolyte–Oxide–Silicon (EOS) system, tunneling current through the gate insulator has been considered as an undesirable factor causing reliability issues such as gate insulator degradation and interface state generation. In this work, [...]

CNT-Array Integrated SoC for Biological Sensor Applications

Seo S.M., Cheon J-H, Lee B-Y, Lee J-H., Lee M., Lee B-Y, Lee J-H., Lee M., Im J., Lee B-Y, Lee J-H., Lee M., Chung I-Y, Hong S., Park Y.J., Min H.S., Seoul National University, KR

8x8 carbon nanotube (CNT) arrays are integrated on top of the CMOS chip. The CNTs are functionalized to detect the target ions, and the I-V characteristics are altered by the bio-chemical reaction. The sensing circuit [...]

CNTs-Insulator- Semiconductor System for Chemical and Biological Sensor Applications

Cheon J-H, Lin Q., Kong B-D, Kang D.W., Kim L., Suh J.S., Park Y.J., Min H.S., Seoul National University, KR

In this paper, an Electrolyte-CNTs-Insulator-Semiconductor capacitor has been prepared due to compatibility with CMOS technology. To prepare this capacitor, we used the bonding technique to combine the MWNT array.It shows that the surface potential modulation [...]
