Research Lines
at EXTREMAT 
The aim of
EXTREMAT research group at the Technical University of Valencia is the synthesis
and the study of the structural, vibrational, optical and electrical properties
of materials under extreme conditions of pressure and temperature.
As can be
observed in the research publications of the group, EXTREMAT has two
main research lines: 1) The study of binary, ternary
and quaternary compounds with interest in Electronics, Optoelectronics and Spintronics. 2) The study of minerals with interest in Geophysics
and Astrophysics.
Among the
studied materials we can find:
§ Binary semiconductors and insulators of several families:
§ III-V family
We have
experience in several semiconductors like GaAs, GaP, InGaAs, as well as AlN, GaN
and InN.
§ II-VI family
We have experience
with semiconductors like ZnO and ZnS.
§ I-VII family
We have experience with semiconductors of the CuBr family.
§ III-VI family
We have broad experience with different semiconductors
of this family like sesquioxides (Al2O3,
In2O3, Tl2O3 and Y2O3)
and layered compounds of tetrahedral coordination (InSe,
GaSe, GaS y GaTe).
§ V-VI family
Our group
has studied several semiconductors of this family like sesquioxides
and sesquichalcogenides (As2O3,
Sb2O3, Bi2O3, Bi2Se3,
Bi2Te3, Sb2Te3).
Some of the sesquichalcogenides behave as 3D
topological insulators at room or high pressure.
§ Ternary semiconductors
and insulators:
§ ABX4 family
Our group has studied different
semiconductors of this family like YVO4, NdVO4, CeVO4,
YLiF4, BiPO4, TbPO4, CaWO4, SrWO4,
PbWO4, BaWO4, HgWO4, and PbMoO4.
§ AB2X4
(II-III2-VI4)
family
Our group has experience in studying different
insulators and semiconductors of this family including oxides and sulphides with spinel-related structure (ZnAl2O4,
ZnCo2O4, ZnMn2O4, and CdIn2S4)
and chalcogenides with defect chalcopyrite and
related structures (CdAl2S4, CdGa2S4,
HgGa2S4, ZnGa2Se4, CdGa2Se4,
HgGa2Se4, and ZnGa2Te4).
