Worldwide, enormous efforts are directed toward the development of the so‐called quantum
internet. Turning this long‐sought‐after dream into reality is a great challenge that will …

The field of nanocatalysis (in which nanoparticles are used to catalyze reactions) has
undergone an exponential growth during the past decade. Two types of studies have been …

Recent advances in the synthesis of semiconductor clusters open a doorway for the
systematic study of size-dependent cluster properties in the condensed phase. This article …

We report ultra-efficient multiple exciton generation (MEG) for single photon absorption in
colloidal PbSe and PbS quantum dots (QDs). We employ transient absorption spectroscopy …

This review is concerned with quantum confinement effects in low-dimensional
semiconductor systems. The emphasis is on the optical properties, including luminescence …

The field of ultrafast spectroscopy of semiconductors and their nanostruc tures continues to
be an active field of research. Exciting new developments have taken place since the first …

Because of the strong spatial confinement of electronic wave functions and reduced
dielectric screening, the effects of carrier-carrier Coulomb interactions are greatly enhanced …

Femtosecond transient absorption in the visible and infrared spectral ranges has been
applied to study carrier dynamics and mechanisms for resonant optical nonlinearities in …

Low-dimensional semiconductor structures, often referred to as nanocrystals or quantum
dots, exhibit fascinating behavior and have a multitude of potential applications, especially …

It is extremely desirable to effectively exploit photo-excited electrons for achieving highly
efficient photocatalytic hydrogen production. Herein, atomically dispersed platinum clusters …
