SUMMARY:Interface Engineering Across Bulk and Mesoscale Quantum Matter
 \, R. G. Herb Condensed Matter Seminar\, Aravind Devarakonda\, Columbi
 a University
DESCRIPTION:Engineering interactions between distinct electronic phase
 s can present new opportunities to discover and control emergent quant
 um phenomena. In this seminar\, I will discuss our group's efforts to 
 realize such interactions through the design of novel interfaces in bu
 lk and mesoscale quantum materials.
\n
\nI will first introduce a grow
 ing family of transition metal dichalcogenide (TMD) bulk van der Waals
  (vdW) superlattices\, where layer-selective chemical substitution pro
 vides a versatile method for tailoring the electronic behavior of TMD 
 layers within high-quality bulk heterostructures. I will focus on our 
 recent work demonstrating how layer-selective rare-earth substitution 
 can dramatically alter the electronic behavior of the TMD monolayers. 
 I will then highlight our broader efforts to expand the ways in which 
 we manipulate and assemble interfaces at the mesoscale\, including tec
 hniques for reconfiguring vdW heterostructures\, methods for creating 
 lateral interfaces between crystalline metals\, and potential strategi
 es for defining interfaces in the absence of crystallographic or compo
 sitional discontinuities.
