Controlled Electroplating of Noble Metals on III-V Semiconductor Nanotemplates Fabricated by Anodic Etching of Bulk Substrates

MONAICO, Elena I.; MONAICO, Eduard V.; URSAKI, Veaceslav V.; TIGINYANU, Ion M. (MDPI (Basel, Switzerland), 2022)

Porous templates are widely used for the preparation of various metallic nanostructures. Semiconductor templates have the advantage of controlled electrical conductivity. Site-selective deposition of noble metal formations, ...
Efectul funcţionalizării cu nanopuncte de Pd ȘI PdO2 a peliculelor de CuO/Cu2O pentru senzori de gaze explozive și volatile

CREŢU, Vasilii; ABABII, Nicolai; POSTICA, Vasile; MAGARIU, Nicolae; TOACĂ, Dan (Agenţia de Stat pentru Proprietatea Intelectuală a Republicii Moldova (AGEPI), 2019)

Proiectul propus are ca scop realizarea cercetărilor aplicative în domeniul nanotehnologiilor, aplicarea metodelor cost-efective pentru sinteza și caracterizarea nanoheterojoncţiunilor fazelor mixte de CuO/Cu2O, funcţionalizarea ...
Electrochemical Deposition by Design of Metal Nanostructures

MONAICO, Ed.; MONAICO, E. I.; URSAKI, V. V.; TIGINYANU, I. M.; NIELSCH, K. (Springer Nature Switzerland, 2019)

We report on the application of specially-designed masks for the purpose of electrochemical etching of InP single crystals which enables one to change in a controlled fashion the direction of propagation of pores, including ...
GaN Ultrathin Membrane for SERS Detection of Rhodamine B

CIOBANU, Vladimir; PLESCO, I.; BRANISTE, T.; CECCONE, G.; COLPO, P.; TIGINYANU, I. (Springer, Cham, 2022)

In this paper we demonstrate the fabrication of a SERS detector based on GaN ultrathin membrane. The GaN membranes are elaborated by the so-called Surface Charge Lithography approach. The obtained membranes are functionalized ...
The impact of morphology upon the radiation hardness of ZnO layers

BURLACU, A.; URSAKI, V. V.; SKURATOV, V. A.; LINCOT, D.; PAUPORTE, T.; ELBELGHITI, H.; RUSU, E. V.; TIGINYANU, I. M. (IOP Publishing, 2008)

It is shown that ZnO nanorods and nanodots grown by MOCVD exhibit enhanced radiation hardness against high energy heavy ion irradiation as compared to bulk layers. The decrease of the luminescence intensity induced by 130 ...
Preparation and Characterization of CdSe Colloidal Quantum Dots by Optical Spectroscopy and 2D DOSY NMR

GERU, I.; BORDIAN, O.; CULEAC, I.; TURTA, C.; VERLAN, V.; BARBA, A. (SPIE, 2015)

We present experimental results on preparation and characterization of colloidal CdSe quantum dots (QD) in organic solvent. CdSe QDs were synthesized following a modified literature method and have been characterized by ...
Production and comparative study of ZnO films obtained by magnetron sputtering, MOCVD and electrochemical deposition

RUSU, E.; BURLACU, A.; ZALAMAI, V.; URSAKI, V.; PRILEPOV, V. (Technical University of Moldova, 2012)

It was found that the morphology, electrical and luminescence properties of ZnO layers obtained by Magnetron sputtering, MOCVD and Electrochemical deposition can be controlled by technological parameters such as the ratio ...
Pulsed Electrochemical Deposition of Pt and Bi2Te3 in Porous Inp: a Comparative Study

MONAICO, Ed.; MONAICO, El.; TIGINYANU, I. (Technical University of Moldova, 2015)

Porous InP templates with parallel pores possessing diameters of 80 nm have been fabricated by anodic etching of commercially available n-InP substrates with (100) orientation in neutral electrolyte (NaCl). Comparative ...
Self-Assembled Monolayer of Au Nanodots Deposited on Porous Semiconductor Structures

TIGINYANU, I.; MONAICO, E.; NIELSCH, K. (The Electrochemical Society, 2015)

We demonstrate the possibility to cover the surface of GaP and InP porous structures by a self-assembled monolayer of electrochemically deposited nanoscale Au nanodots. After nucleation, each dot was found to increase in ...
Synthesis of Colloidal InP Nanocrystal Quantum Dots

SIRBU, L.; GUTUL, T.; TODOSICIUC, A.; DANILA, M.; MULLER, R.; SARUA, A.; WEBSTER, R.; TIGINYANU, I. M.; URSAKI, V. (Technical University of Moldova, 2013)

InP nanodots with the diameter of 4−10 nm were synthesized using sol-gel method. The nanodot dimensions were obtained using TEM, and we found the d(111) spacing to be 0.328nm which agrees within 3% of the literature value. ...
