1 cm(2) CH3NH3PbI3 mesoporous solar cells with 17.8% steady-state efficiency by tailoring front FTO electrodes
(2017)In this article, we investigate the effects of atmospheric-pressure chemical vapour deposited fluorine doped tin oxide (FTO) thin films as front electrodes for the fabrication of mesoporous perovskite solar cells with an ... -
1/f noise in external-cavity InGaN diode laser at 420  nm wavelength for atomic spectroscopy
(2014-03-15)We have extensively studied the frequency noise and relative intensity noise spectra in a tunable external-cavity InGaN diode laser at blue (420 nm) wavelengths. We report flicker (1/f) frequency-noise behavior at low ... -

3D Printed Antennas for MM-Wave sensing applications
(2016-09-03)In this paper, three low cost 3D printed antenna concepts for integration with a mm-wave miniature platform are presented. Proposed antenna solutions are optimized to operate in mm-wave ISM band (122GHz-123GHz). Different ... -
3d Printing on MEMS: Integration of 3d Shock Stopper on a Micro Mirror
(2019)We have developed a polymer-based 3D shock stopper and absorber based on micro stereolithography technology that is integrated onto a prefabricated wafer of a MEMS micro mirror used as a high-power laser steering system. ... -
6 design principles for SLM-based compliant mechanisms
(2019-09-17)This work discusses 6 design principles useful to optimise compliant mechanisms for Additive Manufacturing (AM) and more specifically Selective Laser Melting (SLM). The design principles are: 1) lattice flexures, 2) ... -
6 DOF repeatability measurement setup for measuring position of assembled silicon parts with nanometric resolution.
(2015-06-06)This article presents a test setup dedicated to the measurement of the 6 degrees of freedom relative positioning assembly repeatability of three micro-manufactured parts equivalent to those composing a mesoscale flexure-based ... -
9.6 GHz ultra-low phase noise signal generation from a diode-pumped solid-state laser
(2015-10)We present ultra-low phase noise microwave generation based on a photonics oscillator. By using an ultra-narrow linewidth continuous-wave laser stabilized on a high-finesse optical cavity as a frequency reference, an optical ... -
A 0.5 V 2.5 uW/MHz Microcontroller with Analog-Assisted Adaptive Body Bias PVT Compensation with 3.13nW/kB SRAM Retention in 55nm Deeply-Depleted Channel CMOS
(2019)Microcontroller systems operating at low supply voltage in near or sub-threshold regime suffer both from increased effects of PVT (Process, Voltage, Temperature) variation and from a larger share of leakage on overall power ... -
A 100 kb/s, 4 GHz, 267 mu W Fully Integrated Low Power FM-UWB Transceiver with Multiple Channels
