Improving the characterization of microscopic surface electronic properties is necessary for the miniaturization of electronic devices. Specifically, achieving the ultimate goal of miniaturization, which involves atomic-scale devices such as atomic-scale logic gates [1] and memories [2] composed of dangling bonds on hydrogen-terminated Si surfaces, demands characterization of ultra-small one-...
Top-down approaches have enabled isolation of individual 2-D nanosheets from bulk materials and have revealed extraordinary optical and electronic behaviour at the nanosheet level. An alternate potential approach to fabricate 2-D nanosheets - and materials generally - is to employ a bottom-up strategy using nanostructures as building blocks. This approach affords tunability of material...
Recently, transient nonlinear optical properties of quantum dots have attracted much attention in photonic and plasmonic studies. We have investigated the effect of the decay rate, surface plasmon polariton (SPP) coupling strength, and dipole-dipole interaction (DDI) strength on the time-dependent behavior of the power emitted from a three-level lambda-type quantum dot in plasmonic nanohybrids...
Silicon is the most used material in the electronic industry, with applications in many areas. Although it has excellent electronic properties, Si lacks light emission due to its indirect bandgap. Nonetheless, light emission in silicon nanocrystals due to the quantum confinement effect has been reported. This fact unlocked the potential for silicon-based optoelectronic devices, and many...
Self-assembly is one of the most important bottom-up fabrication strategies to produce two-dimensional (2-d) networks at solid surfaces. Driven by an intricate equilibrium between molecule–molecule and molecule–substrate interactions, these interactions can be used to generate stable extended 2-d geometric structures. For example, halogen-terminated molecules can be activated on surfaces to...
