Strain-Free Epitaxy of Germanium Film on Mica

JAP017741-LIttlejohn-epitaxy-gel.jpg

Germanium was the material of choice in the early history of electronic devices, and due to its high charge carrier mobility, it’s making a comeback. It’s generally grown on expensive single-crystal substrates, adding another challenge to making...

Volatility Surprises Arise in Removing Excess Hydrogen

JCP025741-Dinh-Catalytic-hydrogenation.jpg

Sometimes during catalytic hydrogenation, the partially hydrogenated products become volatile, melting and evaporating away before they can bind to more hydrogen atoms. Now, researchers have explored how and why this volatility varies during...

Soft Magnetic Material Characterizations Get a Harder Look

AIPADV009891-IEM-Machine.jpg

In motors, generators and similar electric machines, the electrical current that powers them generates magnetic fields that magnetize some of the metallic components. Choosing the right magnetic material is crucial for designing efficient machines,...

The Spin Racket: Ping-Pong Champs Are Intuitive Masters of Fluid Dynamics

Curve balls may help a pitcher strike out batters in baseball; and some nasty spin can make an opponent sweat to return a tennis serve. But more so than in any other ball game, in table tennis – where the ball is so light and so small –dedicated...
