Charge Transport
In article number 2300663, Yuan Li and co‐workers report a switch of the tunneling mechanism in protein junctions by change of the environmental conditions, which is achieved by the measurement of ionogel–protein–silver tunnel junctions in either the solid state or water. The person walking straight through the desert represents electron tunneling in the solid state, while the other...
The study of charge transport through proteins is essential for understanding complicated electrochemical processes in biological activities while the reasons for the coexistence of tunneling and hopping phenomena in protein junctions still remain unclear. In this work, a flexible and conductive ionogel electrode is synthesized and is used as a top contact to form highly reproducible protein junctions...
Cobalt silicide has been used in ULSI process from 180nm to 90nm node and beyond. As a conventional self-aligned silicide process procedure [1], cobalt is firstly deposited on cleaned silicon surface, then annealed (450∼600° C) to produce Co2Si or CoSi with resistivity around 100∼150Ω cm. A Hydrochloric and Hydrogen Peroxide Mixture (HPM) was used to strip the unreacted cobalt film from dielectric...
