- Titania thin films with ordered nanostructures are of general interest in fields of photocatalysis, gas sensors, energy storages, energy conversions, etc.
- Lanthanide-doped semiconductors find usage in a wide variety of applications.
- The interest in the study of Ge:Sb:Te thin films is due to their use as optical and electrical memory materials.
- Relaxed InGaN layers have recently gained a lot of interest as potential pseudo-substrates for InGaN-based devices.
- Nanoheteroepitaxial growth of GaN by metal-organic chemical-vapor deposition on dense arrays of (111) Si nanopillars has been investigated.
- Pd-Ag bimetallic nanoparticles have been researched among many fields due to their excellent electronic, catalytic and optical properties.
- Quasicrystals have drawn increased scientific attention during the past decade not only for the purpose of fundamental research, but also due to their possible applications as bulk materials or thin films.
- Threading dislocations (TDs) in (Al,In,Ga)N semiconductors are known to affect the luminescence efficiency of near-band-edge (NBE) emissions in bulk films and quantum structures.
- LSPR arising from free charge carriers in doped metal oxide (MO) nanocrystals (NCs) has been explored abundantly already but there is still much to learn about the effect of dopant identity on the electronic structure of the host and, surface depletion layers.
- Diamond-nitrogen-vacancy (NV) centers show great promise in sensing applications and quantum computing due to their long electron spin coherence time and their ability to be located, manipulated and read out using light. An important breakthrough would be in connecting, using waveguides, multiple diamond NVs together optically. However, the inertness of diamond is a significant hurdle for the fabrication of integrated optics similar to those that revolutionized silicon photonics.
- Resonant tunneling diodes (RTDs) have been extensively studied due to their potential applications in very high speed electronics, optical communications, and terahertz generation.
- Recently a new kind of hybrid micro/nanorod top array has become a promising structure to improve the light extraction efficiency (LEE) of GaN-based light emitting diodes, but simulation of the hybrid structure is extremely difficult owing to the various limitations of different simulation methods.
- As a special order of electronic correlation induced by spatial modulation, the charge density wave (CDW) phenomena in condensed matters attract enormous research interests.
- Two-dimensional electron gas (2DEG) formed at the interface of perovskite oxides has drawn considerable interest due to its rich underlying physics and potential in future generation spin-electronic devices.
- Chirality-based semiconducting nanocrystals, as an emerging area, are envisioned to have great potential in chiral sensing, biomedicine, and chiroptical devices.
- One-dimensional (1D) Te nanostructures are a recent focus in various 1D materials due to their interesting properties of photoconductivity, thermoelectric, catalytic activity and strong piezoelectric effect.
- MoSe2 as a typical transition metal dichalcogenide holds great potential for energy storage and catalysis but its performance is largely limited by its poor conductivity.
- Although extensive experimental and theoretical works have been conducted to understand the ballistic and diffusive phonon transport in nanomaterials recently, direct observation of temperature and thermal nonequilibrium of different phonon modes has not been realized.
