Relying on leading-edge germanium detectors developed by researchers at the Department of Energy’s Oak Ridge National ...

A crystal radio is basically a high Q resonator tied to an antenna and an envelope detector. These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant ...

Haynes put electrodes on both sides of a thin germanium crystal and took very sensitive measurements of the size and speed of the current. Electricity definitely flowed straight through the crystal.

Its melting temperature is 937.4 C. Germanium has the diamond cubic crystal structure shown, an fcc lattice with a basis of two germanium atoms, one at (0,0,0) and the other at (1/4, 1/4, 1/4) in ...

It was made of two gold foil contacts sitting on a germanium crystal. Current coming in one contact would cause the germanium crystal to boost the strength of the current flowing through the other ...

Ever since physicist Ernest Rutherford discovered the atomic nucleus in 1911, studying its structure and behavior has ...

He found an assembled Philmore “selective” radio kit. The simple kit had a coil, a germanium diode, and a crystal earphone. We were sad when [Michael] accidentally burned a part of the radio ...

(Bloomberg) -- Two obscure yet crucial metals, gallium and germanium, are the latest pawns in the escalating US-China trade war. On Dec. 3, China announced an export ban on both metals to the US ...

You benefit from our expertise and years of experience in the field of crystal technology. We manufacture components made from Fluorides (CaF2, BaF2, MgF2), ZnS, Silicon, Germanium or fused Silica ...

Our main infrared optical products include Ge optics / Ge crystal / GaAs / ZnSe, etc. Vital Materials has further increased its production capacity for germanium metal and blanks, now reaching a ...
