0.3V for germanium f V I Figure 2: Diode In Forward and Reverse Modes Almost all diodes are used in such a way that they are forward biased. If too much voltage is placed across the diode in the reverse direction, the diode will begin to conduct, but in a non-controlled and damaging way. There are a few exceptions to this however. A ...

The Forgotten Crystal Radio – Revisited
The diode having a forward voltage (Vf) of less than 300mV works with crystal radios and any diode having its Vf more than 300mV will not work. Vf of 225mV to 250mV is the best choice. You can check the Vf of a diode using a digital multimeter that has Diode Check facility. Fig. 3: Germanium diodes

Semiconductor Diode: Theory, Types & Characteristics
An anode collects the electrons and puts them to use. Semiconductor Diode Definition: A semiconductor diode is the result of the fusion between a small N-type crystal and a P-type crystal, Figure 1. At the junction of the two crystals, the carriers (electrons and holes) tend to diffuse. Some electrons move across the barrier to join holes.

Characteristics of Silicon & Germanium Diodes | Sciencing
Both elements are brittle and have a metallic luster. Each of these elements has an outer electron shell that contains four electrons; this property of silicon and germanium makes it difficult for either element in its purest form to be a good electrical conductor. One way to cause a metalloid to conduct electric current freely is to heat it up.
Semiconductor Diodes
The drawback of silicon, nonetheless, in comparison with germanium, as indicated in Fig. 1.23, may be the increased forward-bias voltage essential to achieve the region of upward movement. It is commonly in the range of 0.7 V for commercially accessible silicon diodes and 0.3 V for germanium diodes when approximated to the …
Figure 1. Diode circuit model
This is an enhanced version of the ideal-diode model presented earlier (see Figure 2) and it is motivated by the full diode model. This model is called the offset diode model (or the 0.7 Volt model). The voltage Vg is called the offset voltage. For silicon diodes Vg=0.7 Volts and for germanium diodes Vg=0.2 Volts.
Basic Electronics
For germanium diodes, n is usually considered to be close to 1. For silicon diodes, n is in the range of 1.3 to 1.6. Note. Ideal Diode Model:Diode is a simple switch that is either closed (conducting) or open (non conducting). Specifically, the diode is a short circuit, like a closed switch, when voltage is applied in the forward direction, and ...

Diodes
A germanium-based diode might be lower, around 0.3V. The type of diode also has some importance in defining the forward voltage drop; light-emitting diodes can have a much larger V F, while Schottky diodes are designed specifically to have a much lower-than-usual forward voltage. Breakdown Voltage

Cut the negative side of the germanium diode lead down to about 5 mm length. The negative side on the 1n34a is the lead closest to the black line indicator seen in Photo 9. 3. Heat the pad that has remaining solder in it and drop the short side lead into the solder. 4. Bend the other lead over like a horseshoe and mate it with the desoldered pad.
Are these germanium diodes?
The package says 2-0q0887. The best I can figure it may be a germanium diode. An ohmmeter reads 00.0. It is red on one end and purple on the other. They look like fuses. 0 ohms is expected for an unblown fuse. Unlikely diodes, as they don't have clearly visible polarity marking and their "legs" are equal length.
Germaniumdiod – Wikipedia
Germaniumdioden var den första dioden tillverkad av halvledarmaterial efter att rörteknologin stod på sin topp. Germaniumdioden uppfanns före den första transistorn (1947) som var tillverkad av just Germanium (och var även av typen PNP ). Den är helt ersatt av Schottkydioden då den senare har avsevärt mindre förluster såsom mindre ...
