Molecular Beam Epitaxy: Types of Growth Modes

Molecular Beam Epitaxy (MBE) is a method of crystal growth for semiconductor and electronic applications. It is an ultrahigh vacuum technique (imagine the vacuum of space!). Semiconductor and metal materials in ‘cups’ are heated to high temperatures such that the materials evaporate out of the cups and condense on a substrate held above the cups. … Continue reading Molecular Beam Epitaxy: Types of Growth Modes

Happy National Nanotechnology Day!

It's 10/9 and you know what that means: National Nanotechnology Day! Today is a day to celebrate all things nano. Why today? Well because 10–9 denotes the prefix 'nano'. So 1x10–9 seconds is a nanosecond and 1x10–9 meters is a nanometer, now thats a small world! But how small is 'nano' exactly? Here are some examples of nano-scale objects: the … Continue reading Happy National Nanotechnology Day!
