Features of the Scanning Tunneling Microscope
The scanning tunneling microscope (STM) invented by Heinrich Rohrer and Gerd Binnig in the 1980s still manages to do a great job today and competes with more advanced microscope types. The scanning tunneling microscope is used for studying the surface atoms that are found on various materials. The...

Nitric Acid
HNO3: A strong acid, it is toxic and can cause severe burns. Transparent colorless or yellowish, fuming, suffocating, caustic and corrosive liquid. Nitric acid boiling point is 83C. A 70 percent solution is used in the S.S.E. laboratory for junction depth measurements. Nitric acid is also present in the metal etch solution used for the Aluminum etch procedure.
