Charging dynamics of InAs self-assembled quantum dots
نویسندگان
چکیده
We present results on the dynamics of the charging of arrays of InAs self-assembled quantum dots ~SAQD’s!. An equivalent circuit used for metal-insulator-semiconductor–field-effect transistor structures is applied and successfully predicts the observed behavior of the capacitance and conductance dependence on the excitation frequency. The Coulomb blockade effect also plays a role in the frequency-dependent spectra. A Coulomb blockade in this system was observed in arrays of over 10 SAQD’s, demonstrating the good size uniformity of such a system. @S0163-1829~97!00932-6#

Wavelength and polarization variations of InAs/GaAs quantum dots emission at liquid Helium temperature via microphotoluminescence spectroscopy
In this paper, we investigate variation of the wavelength, intensity and polarization of the self-assembled InAs/GaAs quantum dots emission by microphotoluminescence spectroscopy at the liquid helium temperature. The microcavity wafer sample is grown by molecular beam epitaxy (MBE) and chemically etched into the micropillar structure (with elliptical cross section - long and short axis 2µm×1.5µ...

متن کاملTemperature influence on optical charging of self-assembled InAsÕGaAs semiconductor quantum dots
It is demonstrated that the photoluminescence spectra of single self-assembled InAs/GaAs quantum dots are very sensitive to excitation energy and crystal temperature. This is qualitatively explained in terms of the effective diffusivity of photogenerated particles, which affects the capture probability of the quantum dot. As a consequence, this opens the possibility of controlling the average n...
متن کاملCoulomb-interaction-induced incomplete shell filling in the hole system of InAs quantum dots.
We have studied the hole charging spectra of self-assembled InAs quantum dots in perpendicular magnetic fields by capacitance-voltage spectroscopy. From the magnetic-field dependence of the individual peaks we conclude that the s-like ground state is completely filled with two holes but that the fourfold degenerate p shell is only half filled with two holes before the filling of the d shell sta...
