Functionalized acenes and heteroacenes for organic electronics.

Pyrene-based materials for organic electronics.

Electroluminescent devices based on organic materials are of considerable interest owing to their attractive characteristics and potential applications to flat panel displays. After a brief overview of the device construction and operating principles, a review is presented on recent progress in organic electroluminescent materials and devices. Small molecular materials are described with emphasis on their material issues pertaining to charge transport, color, and luminance efficiencies. The chemical nature of electrode/organic interfaces and its impact on device performance are then discussed. Particular attention is paid to recent advances in interface engineering that is of paramount importance to modify the chemical and electronic structure of the interface. The topics in this report also include recent development on the enhancement of electron transport capability in organic materials by doping and the increase in luminance efficiency by utilizing electrophosphorescent materials. Of particular interest for the subject of this review are device reliability and its relationship with material characteristics and interface structures. Important issues relating to display fabrication and the status of display development are briefly addressed as well.

Spiro Compounds for Organic Optoelectronics

Despite the high quantum efficiency of solar energy conversion by photosynthesis, practical development of photosynthetic solar energy has been limited so far. One of the main challenges is the relatively poor absorption of photons by photosystems due to narrow absorption spectra, reflection, and respiration. Although most studies focused on increasing the harvesting of photosynthetic electrons (PEs), engineering photon absorption in photosynthesis is another important pathway to pursue for enhancement of photosynthetic solar energy harvesting. Here, plasmonic resonance energy transfer (PRET) from plasmonic nanoparticles to thylakoid membranes (TMs) is proposed to stimulate photosynthesis and increase production of PEs. Gold nanorods (AuNRs), which have a plasmon resonance peak close to 680 nm, are selected to increase the production of high energy PEs by PRET. With AuNR conjugation to spinach TMs, light-triggered PE currents increase to the magnitude 4 fold larger than the currents without the plasmonic AuNRs. Biophotovoltaic (BPV) cells were prepared with the plasmon-enhanced spinach TMs, and they were connected in series and with a capacitor for charge accumulation. The spinach BPVs were charged to achieve high OCP enough to power an LED lamp, demonstrating the feasibility to operate low-power electronics.

This paper presents a micro-power audio continuous-time delta-sigma modulator. Fabricated in a 65nm CMOS process, the modulator occupies 0.14mm2 and achieves 98.2dB DR, 94.1dB SNDR and 107dB SFDR in a 24kHz BW while consuming only 68µW from a 1.2V supply. This results in a Schreier FoM of 183.6 dB, the highest energy-efficiency for audio ADCs published to date.

Light-section (LS)-based range finders are commonly used for obstacle recognition in home service robots and autonomous vehicles. This paper proposes a smart CMOS image sensor for LS-based range finding. The proposed sensor can detect the laser light, even under very strong ambient-illumination levels by using a multiple-capture frame-correlated double sampling (F-CDS), which is realized with an inverter-based switched-capacitor F-CDS accumulator. The proposed sensor also includes on-chip winner-take-all circuits that significantly reduce the software and hardware complexity of interpolation for the subpixel resolution. The prototype chip was fabricated using a 0.35-mum CMOS process. The measurement results show that the proposed sensor can detect a laser line with an intensity that is 56.5 dB lower than that of the ambient illumination, providing a spatial resolution of plusmn0.16 pixels.

This letter presents a low-power continuous-time delta–sigma modulator (CTDSM) that operates at a 0.6-V supply. The loop filter of the CTDSM is realized with inverter-based integrators and negative-R compensation on each integrator’s virtual ground. A body-biasing technique is used for inverters as well as for negative-Rs to ensure robustness against process, voltage, and temperature (PVT) variations. A prototype CTDSM is fabricated in a 28-nm CMOS process and achieves 83-dB SNDR, 84-dB SNR, and 86.5-dB DR in a 40-kHz bandwidth while consuming only 33.6 $\mu \text{W}$ from a 0.6-V supply. This corresponds to the state-of-the-art Schreier FoM of 177.3 dB.
