General Description
Gadolinium arsenide is a compound composed of the rare earth metal gadolinium and the metalloid arsenic. It is a semiconductor material with unique properties, making it potentially useful for various electronic and optical applications. Gadolinium arsenide has a hexagonal crystal structure and is known for its high electron mobility and excellent thermal stability, which makes it suitable for use in high-temperature environments. It has also been studied for its potential application in spintronics, a field of electronics that uses the spin of electrons to store and process information. Additionally, gadolinium arsenide has attracted interest for its potential use in photovoltaic devices due to its strong absorption of infrared light. However, further research is needed to fully understand and harness the potential of gadolinium arsenide for technological applications.
Check Digit Verification of cas no
The CAS Registry Mumber 12005-89-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,2,0,0 and 5 respectively; the second part has 2 digits, 8 and 9 respectively.
Calculate Digit Verification of CAS Registry Number 12005-89:
(7*1)+(6*2)+(5*0)+(4*0)+(3*5)+(2*8)+(1*9)=59
59 % 10 = 9
So 12005-89-9 is a valid CAS Registry Number.

Quaternary rare earth transition metal arsenide oxides RTAsO (T = Fe, Ru, Co) with ZrCuSiAs type structure
Quebe,Terbuechte,Jeitschko
, p. 70 - 74 (2008/10/08)
The equiatomic quaternary compounds RFeAsO (R = La-Nd, Sm, Gd), RRuAsO (R = La-Nd, Sm, Gd-Dy) and RCoAsO (R = La-Nd) crystallize with the tetragonal ZrCuSiAs type structure, which was refined from single-crystal X-ray diffractometer data of PrFeAsO: P4/nmm, Z = 2, a = 398.5(1) pm, c = 859.5(3) pm, R = 0.058 for 167 structure factors and 12 variable parameters. All atomic positions are fully occupied. Chemical bonding in PrFeAsO can be rationalized with oxidation numbers corresponding to the formula Pr+3Fe+2As-3O-2. An electron count of 18 for the iron atoms can only be achieved if Fe-Fe interactions of 281.8 pm pm are considered as bonding.
