Tunable magnetic exchange interactions in manganese-doped inverted core/shell ZnSe/CdSe nanocrystals [PDF]
, 2008 Magnetic doping of semiconductor nanostructures is actively pursued for applications in magnetic memory and spin-based electronics. Central to these efforts is a drive to control the interaction strength between carriers (electrons and holes) and the ...

Dielectric confinement of excitons in type-I and type-II semiconductor nanorods [PDF]
, 2010 We theoretically study the effect of the dielectric environment on the exciton ground state of CdSe and CdTe/CdSe/CdTe nanorods. We show that insulating environments enhance the exciton recombination rate and blueshift the emission peak by tens of meV ...

2D materials and Van Der Waals heterostructures [PDF]
, 2021 In this thesis we have studied several 2D materials as well as a few van der Waals heterostructures. The most famous and probably also most promising 2D material is graphene. Graphene occurs in Nature and the material is stable against ambient conditions, which is extremely beneficial for technological applications. Unfortunately, graphene also has one

Synthesis and thermoelectric properties of noble metal ternary chalcogenide systems of Ag-Au-Se in the forms of alloyed nanoparticles and colloidal nanoheterostructures [PDF]
, 2016 The optimization of a material functionality requires both the rational design and precise engineering of its structural and chemical parameters. In this work, we show how colloidal chemistry is an excellent synthetic choice for the synthesis of novel ...

Perspective on hetero-deformation induced (HDI) hardening and back stress
Materials Research Letters, 2019 Heterostructured materials have been reported as a new class of materials with superior mechanical properties, which was attributed to the development of back stress.

Heterostructure enables new deformation mechanisms to enhance strength and work hardening
Materials Research LettersReflection of geometrically necessary dislocations (GNDs) has been reported effective in increasing strength and ductility of dual-phase alloys. However, this mechanism is rarely observed in conventional single-phase alloys. Here we report the activation

Quantum Communication with Quantum Dot Spins [PDF]
, 2006 Single electron spins in quantum dots are attractive for quantum communication because of their expected long coherence times. We propose a method to create entanglement between two remote spins based on the coincident detection of two photons emitted by
