Abstract Two-dimensional (2D) atomic crystals, such as graphene and transition-metal
dichalcogenides, have emerged as a new class of materials with remarkable physical …

This textbook describes the physics of semiconductor nanostructures with emphasis on their
electronic transport properties. At its heart are five fundamental transport phenomena …

We consider a clean two-dimensional electron liquid in a weak magnetic field where N≫ 1
lower Landau levels are completely filled, while the upper level is only partially filled. Due to …

We report on optical measurements of a two-dimensional electron gas near the metal-
insulator transition. We observe the appearance of excitons and negatively charged …

The random positions of ionized-impurity ions in doped heterostructures give rise to a
random potential, which we have analyzed using a self-consistent method that includes …

The emission and absorption spectra of quantum wells containing electron or hole gas are
reviewed. We show that trions, also known as charged excitons, play a dominant role in …

We calculate the distribution of incompressible and compressible regions at an
electrostatically defined edge of a two-dimensional electron system (2DES) in a strong …

Just as photons are the quanta of light, plasmons are the quanta of orchestrated charge-
density oscillations in conducting media. Plasmon phenomena in normal metals …

By analyzing the temperature (T) and density (n) dependence of the measured conductivity
(σ) of two-dimensional (2D) electrons in the low-density (∼ 10 11 cm− 2) and temperature …

We report the first experimental observation of a magnetic-field-induced transition from an
Anderson insulator to a quantum Hall conductor in a two-dimensional electron gas (2DEG) …
