Electro-optic spatial light modulator from an engineered organic layer


Abstract "Tailored nanostructures provide at-will control over the properties of light, with applications in imaging and spectroscopy. Active photonics can further open new avenues in remote monitoring, virtual or augmented reality and time-resolved sensing. Nanomaterials with χ(2) nonlinearities achieve highest switching speeds. Current demonstrations typically require a trade-off: they eith... » read more

Inverse Design of Inflatable Soft Membranes Through Machine Learning


Abstract "Across fields of science, researchers have increasingly focused on designing soft devices that can shape-morph to achieve functionality. However, identifying a rest shape that leads to a target 3D shape upon actuation is a non-trivial task that involves inverse design capabilities. In this study, a simple and efficient platform is presented to design pre-programmed 3D shapes starting... » read more

Metasurface Colloidal Quantum Dot Photodetectors


Abstract: "Efficient photodetectors that can be easily engineered for a specific spectral window are of high interest. Here, we report on the design, fabrication, and characterization of metasurface-enhanced photodetectors and photodiodes using colloidal quantum dots. We fabricate photoconductors optimized for the wavelength range around 1550 nm featuring responsivities of up to 8000 A/W wit... » read more

Hybrid architecture based on two-dimensional memristor crossbar array and CMOS integrated circuit for edge computing


Abstract "The fabrication of integrated circuits (ICs) employing two-dimensional (2D) materials is a major goal of semiconductor industry for the next decade, as it may allow the extension of the Moore’s law, aids in in-memory computing and enables the fabrication of advanced devices beyond conventional complementary metal-oxide-semiconductor (CMOS) technology. However, most circuital demons... » read more

A Comparative Analysis of Computer-Aided Design Tools for Complex Power Electronics Systems


Abstract: "Companies working on semiconductors must currently assure the customers of not only the performance of the semiconductor device per se, but also its performance when it is implemented in a real board, therefore including the role of parasitic effects. It is therefore very important to evaluate, especially during the design phase, not only the single device, but the complete board ... » read more

X-ray Imaging of Silicon Die Within Fully Packaged Semiconductor Devices


Abstract: "X-ray diffraction imaging (XRDI) (topography) measurements of silicon die warpage within fully packaged commercial quad-flat no-lead devices are described. Using synchrotron radiation, it has been shown that the tilt of the lattice planes in the Analog Devices AD9253 die initially falls, but after 100 °C, it rises again. The twist across the die wafer falls linearly with an incre... » read more

Screen Printed Chipless RFID Tags on Packaging Substrates


Abstract: "A chipless radio frequency identification (RFID) tag is a suitable low-cost alternative to any chip-based RFID one. The flexibility to use low-cost printing techniques makes chipless RFID a competitive technology. In this paper, we report an evaluation of the microwave performance of two different screen-printed chipless tags in the 3–6 GHz range. The tags were designed and scre... » read more

Reasserting U.S. Leadership in Microelectronics (MIT)


In this new paper, MIT researchers lay out a vision and approach for how universities can help the U.S. regain leadership as a semiconductor superpower. The paper looks at education and workforce development, research, technology translation, startups, intellectual property, academic infrastructure and regional network efficiencies. Find the paper here and the MIT news writeup from 1/19/2022... » read more

Storing and Reading Information in Mixtures of Fluorescent Molecules


Abstract "The rapidly increasing use of digital technologies requires the rethinking of methods to store data. This work shows that digital data can be stored in mixtures of fluorescent dye molecules, which are deposited on a surface by inkjet printing, where an amide bond tethers the dye molecules to the surface. A microscope equipped with a multichannel fluorescence detector distinguishes ... » read more

Energy Harvesting and Power Management for IoT Devices in the 5G Era


Abstract: "The fifth-generation (5G) network is a fast-growing technology that impacts personal devices for both society and the economy. With the widespread Internet of Things (IoT) devices in such networks, powering and exploring energy to operate them is vital in the 5G era. Therefore, projecting and forecasting how to power IoT devices in the 5G network have already begun, with an aspira... » read more
