- n. A brittle, crystalline, gray-white metalloid element, widely used as a semiconductor, as an alloying agent and catalyst, and in certain optical glasses. Atomic number 32; atomic weight 72.59; melting point 937.4°C; boiling point 2,830°C; specific gravity 5.323 (at 25°C); valence 2, 4. See Table at element.

- n. A rare element, discovered in 1885 in a silver ore (argyrodite) at Freiberg. It is a brittle, silver-white metal, chemically intermediate between the metals and nonmetals, resembles tin, and is in general identical with the predicted ekasilicon. Symbol Ge. Atomic number 32. Atomic weight 72.59. It has excellent semiconductor properties, and is used in transistors and diodes.

- n. Chemical symbol, Ge; specific gravity, 5.469; atomic weight, 72.3. An element discovered in 1885 by Winkler in the mineral argyrodite, which is a sulphid of germanium and silver.
- n. The discovery of this chemical element in 1885 constituted the third verification of Mendelejeff's prediction that elements, unknown when his periodic law was pointed out, would later be discovered having approximately certain atomic weights and certain properties which he indicated. Germanium has been found in argyrodite from Saxony and also in minerals from Bolivia.

- n. a brittle grey crystalline element that is a semiconducting metalloid (resembling silicon) used in transistors; occurs in germanite and argyrodite
Clemens Winkler named germanium from the Latin word Germania meaning Germany.
a simple integrated circuit in germanium, a commonly used semiconductor at that time.
The project I worked on was the measurement of the lifetime of photo-excited carriers in germanium.
Unlike bulk germanium, which isn't flexible and is highly brittle, the fabric created from nanowires is flexible and is as strong as Kevlar.
Xilingol, it turns out, may have China's largest deposit of germanium, which is found in the dust of the local brown coal.
The semiconductors now in use are artificial products made from elements such as germanium or silicon.
a mineral called germanium that helps in avoiding cancer.
This issue has led to a wave of active development of next-generation transistors using materials such as germanium, gallium arsenide, or graphene as channel materials.
Additionally, hospitals and research institutions across the nation use isotopes such as germanium-68, produced by this facility, every day to calibrate medical imagining equipment.
For each of the four evening experimental sessions, Dr. Creath and I placed four germanium leaves, as well as four geranium flowers, in a completely dark, light-tight chamber that was housed in a light-tight darkroom.
