These days the envelope detector is a point contact diode such as a 1N34 Germanium diode. The resonant circuit passes a specific wavelength (or more specifically range of wavelengths depending on ...

During WWII, germanium was primarily used in point-contact diodes for radar pulse detection. After the war, from the 1950s to the early 1970s, germanium’s development as a semiconductor in transistors ...

With nothing more complex than a germanium point-contact diode and an oscilloscope, you can quickly, easily, and cheaply resolve microwave signals, as we are shown with a 2.4GHz wireless mouse.

Voila: two gold contacts just a hair-width apart. The whole triangle was then held over a crystal of germanium on a spring, so that the contacts lightly touched the surface. The germanium itself ...

Many people giving talks had complained about the current germanium transistors -- they had a bad habit of not working at high temperatures. Silicon, since it's right above germanium on the ...

Scientists of the MPI for Nuclear Physics (MPIK) initiated the GERDA experiment in 2004, in order to check the results of the Heidelberg-Moscow experiment by using an innovative shielding approach in ...
