· O8 Cu4 Ho2

O8Cu4Ho2 is an experimental intermetallic compound combining copper with holmium (a rare-earth element) in an oxygen-rich ceramic matrix, positioned in the semiconductor class. This material represents active research into rare-earth copper oxides, which are being investigated for their potential magnetic, electronic, and thermal properties that could enable applications beyond conventional semiconductors. The combination of transition metal (copper) and lanthanide (holmium) elements suggests potential use in specialized electronic or photonic devices where rare-earth contributions to band structure or magnetic ordering are advantageous.
