Revealing the Hidden Role of Cd in p‐Type Mg3Sb2: Enhanced Thermoelectric Performance by Grain Boundary Segregation Engineering

Advanced Functional Materials, EarlyView.
The hidden role of Cd segregation at grain boundaries is revealed in p‐type Mg3Sb2 by atom probe tomography and other advanced characterizations. Grain boundary Cd enrichment suppresses the SbMg+ hole‐killer formation and lowers potential barriers, enhancing electrical conductivity.

High-Bandwidth Solid-State Nanopore Sensors [PDF]

Biophysical Journal, 2012
Nanopores are attractive electrochemical sensors for their single-molecule sensitivity and simple experimental setup. Many of the electronic systems used for nanopore measurements are inherited from electrophysiology applications, and as a result they are primarily optimized for current levels of 50pA or less, at bandwidths below 10kHz.
