My name is Ashley Mila and I am originally from Miami, FL and currently pursuing a double degree in Biology and Criminology on a pre-med track. My research interests are inorganic material synthesis and magnetic behaviors. Besides research, I also work as medical assistant and Chemistry tutor and I am currently earning my Emergency Medical Responder certification. Upon graduation, I hope to attend medical school and become a reconstructive plastic surgeon.

Intercalation of Magnetic Properties of Iron Intercalated Vanadium DiTelluride

Abstract

Layered two-dimensional materials, such as transition metal dichalcogenides
(TMDs), express magnetic and electronic properties that could make them useful
in a variety of electronic devices, such as MRIs or photodetectors. However,
metallic TMD’s have limitations to real world applications, namely structural
instability under ambient conditions. The Shatruk lab has previously
demonstrated that light transition metal intercalation can stabilize VTe2 and
promote ferromagnetic (FM) ordering. Intercalation studies using Cr reveal
complex structures with some Cr substitution of in-layer V atoms as well as light.
In this research, we investigate the intercalation
of Fe into the VTe2 to produce new, air-stable
crystalline compositions of Fe0.3V0.6Te2,
Fe0.4V0.7Te2, Fe0.5V0.5Te2, and Fe0.5V1.2Te2. Here
we present the elemental and structural
characterization of the compounds. Our results
have revealed that Fe, like Cr, undergoes a
complex combination of substitution and
intercalation which ultimately stabilizes VTe2,
yielding a more thermodynamically stable
material which is less air-sensitive and may
exhibit ferromagnetic ordering.
