Journal ArticleDOI
Langmuir−Blodgett Film Deposition of Metallic Nanoparticles and Their Application to Electronic Memory Structures
Shashi Paul,C. Pearson,A. Molloy,M. A. Cousins,M. Green,S. Kolliopoulou,Panagiotis Dimitrakis,Pascal Normand,Dimitris Tsoukalas,Michael C. Petty +9 more
TL;DR: In this article, a monolayer of organically passivated gold nanoparticles has been incorporated into a metal-insulator-semiconductor (MIS) structure, which exhibits a hysteresis in its capacitance versus voltage characteristic, the magnitude of which is dependent on the voltage sweep conditions.
Journal ArticleDOI
Charge storage and interface states effects in Si-nanocrystal memory obtained using low-energy Si + implantation and annealing
E. Kapetanakis,Pascal Normand,Dimitris Tsoukalas,Konstantinos Beltsios,J. Stoemenos,S. Zhang,J. A. van den Berg +6 more
TL;DR: In this article, the potential of thin SiO2 oxides implanted by very low energy (1 keV) Si ions and subsequently annealed are explored with regards to their potential as active elements of memory devices.
Journal ArticleDOI
Structural and electrical properties of silicon dioxide layers with embedded germanium nanocrystals grown by molecular beam epitaxy
Aloke Kanjilal,J. Lundsgaard Hansen,Peter I. Gaiduk,A. Nylandsted Larsen,Nikolay Cherkashin,Alain Claverie,Pascal Normand,E. Kapelanakis,D. Skarlatos,Dimitris Tsoukalas +9 more
TL;DR: A sheet of spherical, well-separated, crystalline Ge nanodots embedded in SiO2 on top of a p-(001)Si wafer was fabricated by molecular beam epitaxy (MBE) combined with rapid thermal processing and characterized structurally and electrically as mentioned in this paper.
Journal ArticleDOI
Hybrid silicon-organic nanoparticle memory device
S. Kolliopoulou,Panagiotis Dimitrakis,Pascal Normand,Hao-Li Zhang,N. Cant,Stephen D. Evans,Shashi Paul,C. Pearson,A. Molloy,Michael C. Petty,Dimitris Tsoukalas +10 more
TL;DR: In this paper, a nonvolatile electrically erasable programmable read-only memory device using gold nanoparticles as charge storage elements deposited at room temperature by chemical processing is demonstrated. But the device exhibits significant threshold voltage shifts after application of low-voltage pulses (⩽±6 V) to the gate and has non-volatile retention time characteristics.
Journal ArticleDOI
A miniature pressure system with a capacitive sensor and a passive telemetry link for use in implantable applications
TL;DR: In this paper, a miniature telemetric pressure-measuring system is presented, which uses passive telemetry to transfer power to the transponder and pressure data to the remote base unit.
