1D Quantum Chains

We have developed a method for the fabrication of ultra-short (7 to 200 atoms long) atomic chains. This method uses metal phthalocyanine (MPc) thin films and superlattices (SLs). MPcs are flat molecules that can host different metal ions in their center. When grown in thin films and SLs, these molecules stacks face-to-face giving rise to ordered arrays of 1D chains. Particularly, iron-phthalocyanine (FePc) is magnetic. The use of thin films and SLs molecules allow precise control of the chain length and composition.


Using these low dimensional systems we want to address one of the fundamental problems in magnetism; the determination of the extent and persistence of short- and long-range interactions in 1D-atomic chains. Also, intercalating different MPc species in a SL structure we want to control the spin along the chains to produce 1D-System as the ones predicted by Haldane (see Nobel Prize 2016).

The objective of this work is to fabricate large amounts of magnetic nanostructures with specific shapes to control their magnetic properties. The composition of the nanostructures can be modulated (layer by layer) to give rise to different magnetic behavior such as exchange bias, In-plane or out-of-plane magnetic anisotropy, and magnetic vortex state.


These fully-tunable magnetic nanostrucutres present a high potential for MRI image contrast improvement and medical therapies such as hyperthermia.

One of the challenges of current technology is to use light to write and read a memory element. Using inexpensive techniques such as chemical electrodeposition and coaxial lithography, varying composition nanorods are fabricated to study the interaction between plasmons and magnetic moments. The aim of this research is to explore and understand the magneto-optical coupling in these nanostructures to develop new ultra-fast memories that can be controlled by light. 

Work in collaboration with Dr. Kathryn Mayer (UTSA) and Dr. Nicolas Large (UTSA).



We have developed a method for the fabrication of vertical stakings of layers consisting of ultra-dense arrays of nanorods. These structures present two advantages, they possess a high surface area to volume ratio, and since the aspect ratio of the nanorods can be tuned at will, each layer can be designed with a specific plasmon resonance frequency. This allows the use of light excitation to induce Localized Surface Plasmon Resonance and efficient heating.


We aim to speed up and improve catalytic reactions using these nanostructures as electrodes.
