With further progress in dopant engineering, a controlled design of dopant-based single-electron memory devices, working on a principle as described here, could become feasible [40].
Nanosilicon materials are promising systems for the fabrication of single-electron transistor (SET) and memory devices in silicon.
In this work, we review our most recent studies on key atom devices with fundamental structures of silicon-on-insulator MOSFETs, such as single-dopant transistors, preliminary memory devices, single-electron turnstile devices and photonic devices, in which electron tunneling mediated by single dopant atoms is the essential transport mechanism.
Ability to create ordered QD structures, i.e. deterministically positioned QDs, is essential for enabling new optical and electronic applications, such as single-photon emitters, single-electron transistors, or QD-based memory devices.
Since the leaking possibility of the electrons is increasing, conventional FG memory devices are resulting in poor reliability and retention.
The trap lifetime of the electrons and holes in the memory devices is calculated by first finding the back-tunneling probability (T) [17, 23]: mathrm{T}=16times left(frac{E_0}{V_0}right times left 1-frac{E_0}{V_0}right)times {e}^{-2d frac{sqrt{2{m}_0left 1-frac{E_00 right)}{{hslash }} (1).

During the reverse sweep, the current increased in all memory devices due to a trapped electron at the AuNP sites[1].
The presence of oxygen-deficient TaO x conducting filaments is investigated by Auger electron spectroscopy (AES) before and after switching of the memory devices.
Using specially designed 'spin memory' devices we optically generate and orientate individual electron spins in quantum dots with the frequency selectivity provided by optical excitation.
The cross-point memory devices are observed by high-resolution transmission electron microscopy (HRTEM).
