Journal ArticleDOI
Engineering Graphene Quantum Dots for Enhanced Ultraviolet and Visible Light p-Si Nanowire-Based Photodetector
TL;DR: In this work, a significant improvement of the classical silicon nanowire (SiNW)-based photodetector was achieved through the realization of core-shell structures using newly designed GQDPEIs via simple solution processing.
Journal ArticleDOI
High-performance solid state supercapacitors assembling graphene interconnected networks in porous silicon electrode by electrochemical methods using 2,6-dihydroxynaphthalen
Cosmin Romanitan,Pericle Varasteanu,Iuliana Mihalache,Daniela C. Culita,Simona Somacescu,Razvan Pascu,Eugenia Tanasa,Sandra A. V. Eremia,Adina Boldeiu,Monica Simion,Antonio Radoi,Mihaela Kusko +11 more
TL;DR: The achievement of an easy scalable technology for solid state supercapacitors on silicon, with excellent electrochemical properties, is demonstrated, comparable to many of the best high-power and/or high-energy carbon-based super capacitors, their figures of merit matching under battery-like supercapACitor behaviour.
Journal ArticleDOI
The Mechanical and Physical Properties of 3D-Printed Materials Composed of ABS-ZnO Nanocomposites and ABS-ZnO Microcomposites
Nectarios Vidakis,Markos Petousis,Athena Maniadi,Emmanuel Koudoumas,George Kenanakis,Cosmin Romanitan,Oana Tutunaru,Mirela Petruta Suchea,John Kechagias +8 more
TL;DR: Comparing the two composites, it was found that the ABS/ZnO microcomposite structures had higher overall mechanical strength over ABS/ ZnO nanostructures.
Journal ArticleDOI
Very large phase shift of microwave signals in a 6 nm Hf x Zr 1− x O 2 ferroelectric at ±3 V
Mircea Dragoman,Mircea Modreanu,Ian M. Povey,Sergiu Iordanescu,Martino Aldrigo,Cosmin Romanitan,Dan Vasilache,Adrian Dinescu,Daniela Dragoman +8 more
TL;DR: This letter reports for the first time very large phase shifts of microwaves in the 1-10 GHz range, in a 1 mm long gold coplanar interdigitated structure deposited over a 6 nm Hf x Zr1-x O2 ferroelectric grown directly on a high resistivity silicon substrate.
Journal ArticleDOI
Synthesis and characterization of Ca doped ZnO thin films by sol–gel method
Anca-Ionela Istrate,F. Nastase,Iuliana Mihalache,Florin Comanescu,Raluca Gavrila,Oana Tutunaru,Cosmin Romanitan,Vasilica Tucureanu,Monica Nedelcu,Raluca Muller +9 more
TL;DR: In this article, the structural changes in the molecular binding between ZnO and Ca, Fourier Transform Infrared spectroscopy (FTIR), Micro-Raman Spectroscopy and X-ray diffraction (XRD) were performed.
