Why?  We were the only analyst to correctly predicted 2021's supercycle and product shortages at last year's IFS event, based on our proven methodology and 55 plus years of direct industry experience, longer than any other analyst and most industry execs. Now in its 34th year, our experience and track record makes this a must-attend event for key decision makers in the semiconductor, electronics and all related industries. We pride ourselves on the integrity of our work and the rigour and discipline employed in everything we do, not least of which is our commitment to accurate and usable information. We are never afraid take a contrarian view, backed up by data and sound analytical process, which is why our industry forecasts have consistently proved both accurate and insightful, second to no-one. Find out what's in store for 2022 at IFS2022, Future Horizons' annual industry outlook webinar.

[paper] Ultrafast imaging of THz electric waveforms using quantum dots

Moritz B. Heindl, Nicholas Kirkwood, Tobias Lauster, Julia A. Lang, Markus Retsch, Paul Mulvaney and Georg Herink;
Ultrafast imaging of terahertz electric waveforms using quantum dots;
Light: Science & Applications; Vol. 11, No. 5 (2022)
DOI: 10.1038/s41377-021-00693-5

AbstractMicroscopic electric fields govern the majority of elementary excitations in condensed matter and drive electronics at frequencies approaching the Terahertz (THz) regime. However, only few imaging schemes are able to resolve sub-wavelength fields in the THz range, such as scanning-probe techniques, electro-optic sampling, and ultrafast electron microscopy. Still, intrinsic constraints on sample geometry, acquisition speed and field strength limit their applicability. Here, we harness the quantum-confined Stark-effect to encode ultrafast electric near-fields into colloidal quantum dot luminescence. Our approach, termed Quantum-probe Field Microscopy (QFIM), combines far-field imaging of visible photons with phase-resolved sampling of electric waveforms. By capturing ultrafast movies, we spatio-temporally resolve a Terahertz resonance inside a bowtie antenna and unveil the propagation of a Terahertz waveguide excitation deeply in the sub-wavelength regime. The demonstrated QFIM approach is compatible with strong-field excitation and sub-micrometer resolution introducing a direct route towards ultrafast field imaging of complex nanodevices in-operando.

The absorption of ultrashort visible sampling pulses (green) is modulated via the quantum-confined Stark effect in a layer of nanocrystals (red); b.) The THz-induced change in the QD band structure can increase the absorption and translates to enhanced luminescence emission, accessible by optical microscopy. The modulated fluorescence yield SQFIM = STHz−S0 encodes the instantaneous local electric field and snapshot images resolve the spatio-temporally evolution of the near-field waveform

Abstract: This paper reviews the recently-developed class of band-modulation devices, born from the recent progress in fully-depleted silicon-on-insulator (FD-SOI) and other ultrathin-body technologies, which have enabled the concept of gate-controlled electrostatic doping. In a lateral PIN diode, two additional gates can construct a reconfigurable PNPN structure with unrivalled sharp-switching capability. We describe the implementation, operation, and various applications of these band-modulation devices. Physical and compact models are presented to explain the output and transfer characteristics in both steady-state and transient modes. Not only can band-modulation devices be used for quasi-vertical current switching, but they also show promise for compact capacitorless memories, electrostatic discharge (ESD) protection, sensing, and reconfigurable circuits, while retaining full compatibility with modern silicon processing and standard room-temperature low-voltage operation.
