Probe assisted localized doping of aluminum into silicon substrates

Author(s)
Jungjoon Ahn, Santiago D. Solares, Lin You, Hanaul Noh, Joseph Kopanski, Yaw S. Obeng
In this paper, we demonstrate AFM probe assisted deterministic doping (PADD) of Al into an n- type Si (100) wafer, to generate nanoscale counter-doped junctions

Background: Over 2000 people a year in the UK need a bone marrow or blood stem cell transplant. It is important to accurately quantify the haematopoietic stem

Fast quantification of nanorod geometry by DMA-spICP-MS

Author(s)
Jiaojie Tan, Yong Yang, Hind El Hadri, Mingdong M. Li, Vincent A. Hackley, Michael R. Zachariah
A fast, quantitative method for determining the geometries of nanorods (i.e., length and dimeter) is described, based on hyphenation of differential mobility

The effect of solvent extraction on pore space was examined on a suite of samples from the Eagle Ford Shale Formation with varying lithologies and maturities

Porous Zero-Mode Waveguides for Picogram-Level DNA Capture

Author(s)
Vivek Jadhav, David Hoogerheide, Jonas Korlach, Meni Wanunu
We have recently shown that nanopore zero-mode waveguides are effective tools for capturing picogram levels of long DNA fragments for single-molecule DNA

Low-Carrier Density and Fragile Magnetism in a Kondo Lattice System
