a lil help? (1 Viewer)

[brilliance**]

hey guys.... just a simple question that I'm kinda stuck on for an assessment - based on superconductors:

- Name some examples of metals, metal alloys and compounds which are superconductors.

I can't seem to find much on google except for ..... mercury, and some other complex ones.
Does anyone know where I could find anymore info on superconductors .&etc. ?//
thanks heaps in advance.

Superconductivity occurs in a wide variety of materials, including simple elements like tin and aluminium, various metallic alloys, some heavily-doped semiconductors, and certain ceramic compounds containing planes of copper and oxygen atoms...

For some more information, click here. Hope that helped.

These are just some examples of compounds used for superconductivity from Excel HSC Physics:

SnSe2(Co(C5H5)2)0.33
PbMo6S8
Cs3C60
NbGe
Nd1.85Sr0.15CuO4
Ba0.6K0.4BiO3
La1.85Sr0.15CuO4
YBa2Cu3O7
Bi2Sr2Ca2Cu3O10
Tl2Ba2Ca2Cu3O10
HgBa2Ca2Cu3O8+x

I guess you're using an old textbook, huh?

Here are some cool superconductors, from my new one:

Name of element/alloy | Critical temperature (temp when it becomes superconductor)

Niobium-aluminium-germanium | 21K(kelvin)

Tin-niobium | 18K

YBCO | 90K

HgBa2Ca2Cu3O8 | 133K

The textbook isn't old. I doubt they'd list all the superconductors, though.

i also need some help for an assessment task about photocells including a picture any help would be appreciated

• describe and explain how photocells(photodetectors) work include a picture showing parts, electron flow, holes direction and current flow direction
