Metalattices fill a gap in length scales between atomic and photonics crystals
Metalattices fill a gap in length scales between atomic and photonics crystals. At length scales of tens of nanometers, old materials in new periodic forms are expected to exhibit different properties as the sizes of their meta-atoms and meta-bonds become

DESCRIPTION

IRG3 exploits unique synthetic capabilities in high-pressure infiltration of semiconductors into diverse 3D nanotemplates to create new materials in which electronic, magnetic, and vibrational degrees of freedom interact with well-ordered nanometer-scale 3D structural modulations. Ordered, electrically continuous 3D structural modulations of extreme strain, quantum confinement, and interfacial physics will define a new physical regime for electronic, optical, magnetic, and thermal response, one that exploits diffraction effects to control thermal and electrical transport. The greatly altered palette of physical properties thereby made available in well-developed semiconductor platforms such as Si could enable practical application in diverse areas such as solar cells, near-IR photonics, light emitting devices, and improved thermoelectrics.
