Curriculum Vitae
   

Dr. Alexandru Müller, Ph.D. in Semiconductor Physics, since 1990

Employment 1972 -1996 ICCE Bucharest (microwave devices group head); 1996-prersent:IMT Bucharest head of the Micromachined structures, microwave circuits and devices laboratory

Most important results obtained in the period 1972-1996
The design and manufacturing of the first Romanian silicon and GaAs based microwave diodes: pin diodes for switching applications in the 2-20 GHz range, abrupt and hyper-abrupt tuning varactor diodes, step-recovery diodes (SRD) for frequency multipliers with fout in the range 4-18 GHz; GaAs Schottky and Gunn diodes. Development of novel technological processes for manufacturing these type of devices;

 

The elaboration of an original approach for the switching behavior of a narrow base pin diodes, with practical results for maximizing the stored charge (and efficiency) of SRDs (A Müller and S Voinigescu, Solid State Electronics 1989, 32, 593); S. Voinigescu, A. Müller, et. al, Solid State Phenomena1989, 6&7, 315). This was one of the main topics of the PhD thesis (1990).

The original approach was successful used in obtaining very efficient SRDs. Maximizing the doping level in the p+ layer ICCEs SRD had a better efficiency in the X8 multipliers (from 05 to 4 GHz) than all similar devices fabricated by famous providers like Thomson, Microwave Associates, Varian etc.

Most important results obtained in the period 1996-present
The manufacturing of membrane supported mm wave circuits microwave passive circuits supported on 1.5 µm thin dielectric membranes (SiO2/Si3N4/SiO2) obtained by Silicon micromachining, an European priority in this new topics (A. Müller, et al, European Semiconductor, 1997, 11, 27)

In 1997 Dr. Müller won, as coordinator, the FP4 Project No 977131 “Micromachined Circuits for Microwave and Millimeter Wave Applications” MEMSWAVE. It was one of the first EU projects in the RF MEMS topics, with 9 partners from 6 countries. It was the first ICT European project coordinated (and for a long time the only one) by an Eastern Europe country. The results obtained in the frame of this EU project have contributed to the SoTA in the topic. In 2002 the project was nominated between the 10 finalists for the Descartes prize of the EC 2002. The project has generated an itinerant European workshop in RF MEMS called “MEMSWAWE” (first 2 editions in Sinaia 1999 and 2001). The manufacturing of first membrane supported mm wave filters and antennae for mm wave frequencies (38 GHz, 60 GHz and 77 GHz) and of a micromachined receiver module for mm wave frequencies with the antenna and the Schottky diode, monolithic integrated on the same 2 µm thin GaAs membrane (A. Müller et. al, JMM, 2001, 11, 1; A. Müller, et. al, JMM, 2000, 10, 130, G. Konstantinidis, A. Müller, JMM, 2003, 13, 353).

Leader of IMT group in: FP6 NoE in RF MEMS, AMICOM, (coordinated by LAAS CNRS Toulouse); FP7 IP projects SMARTPOWER (2011-2016), NANOTEC (2011-2015), ENIAC “SE2A” (2008-2012), “MERCURE” (2010-2014);

Coordinator of: FP7 REGPOT project MIMOMEMS “European Centre of Excellence in Microwave, Millimeter Wave and Optical Devices based on Micro-Electro-Mechanical Systems for Advanced Communication Systems and Sensors” (2008-2011). This project has ensured the SoTA results obtained in research in MEMS microwave/mm wave circuits, Dr. A Müller co-authoring papers in prestigious journals like IEEE MTT, IEEE Microwave Antennas and Propagation and Applied Phys. Let., JMM. etc. Apart from the support for scientific activities this project together with national projects SIMCA (Capacities) and Microlab (Module 4) ensured the actual SoTA infrastructure of the lab including complete microwave/mm-wave characterization equipment.

Dr. Müller is now coordinating the ESA project “Microwave filter based on GaN/Si SAW resonators operating at frequencies above 5 GHz” (2015-2017) and the H2020 Marie Curie - SelectX “Integrated Crossbar of Microelectromechanical Selectors and Non-Volatile Memory Devices for Neuromorphic Computing” (2016-2018) (he is the “supervisor”).

Dr. Müller was coordinator of national projects in PN I, CEEX, PN II and STAR programs, projects obtained as result of a national competition:
PN I - MATNANTECH Program: COMPOLIMEMS (2001-2004), SIRMEMS (2002-2005), FIREMEMS (2004-2006),
CEEX Program: ACOMEMS (2006 – 2009), Capacities SIMCA (2007 -2009).
PN II projects: MIMFOMEMS (2007 – 2010), GIGASABAR (2008 – 2011), IDEAS MIFOGAN (“Novel technologies based on micromachining and nano-processing of GaN/Si, for advanced microwave and photonic devices” 2011 - 2016)
STAR - M3GAAS (“Millimetre and submillimeter wave GaAs Schottky diodes detectors and mixers” 2013 - 2016).
Now he is the coordinator of the PN II project Partnership SETSAL (“Temperature sensor based on GHz operating AlN/Si SAW structures“ 2014 -2017).

In the last years Dr. Müller has obtained very new results in manufacturing of FBAR and SAW on GaN/Si resonators operating in the GHz frequency range as well as and temperature and pressure sensors based on GaN/Si. Also Dr Muller worked on analysis and application in sensors of superior propagation modes in GaN/Si and GaN membranes (Sezawa, respectively Lamb modes). These results represent the state of the art for this type of devices and were published in top journals in the topics (A. Müller et al IEEE Electron Devices Lett., vol. 36, 12, 2015; A. Müller, et. al, Sensors and Actuators A, 209, 2014; A. Müller, et al, Thin Solid Films, 2012, 520, 6; A. Müller, et al. IEEE Electron Devices Lett. , 2010, 31, 12; A.
