Design Of Analog Cmos Integrated Circuits

We demonstrate first room temperature, and ultrabright single photon emission from a color center in two-dimensional multilayer hexagonal boron nitride. Density Functional Theory calculations indicate that vacancy-related centers are a likely source of the emission.

Quantum emission from hexagonal boron nitride monolayers

Quantum emitters (QEs) in 2D hexagonal boron nitride (hBN) are extremely bright and are stable at high temperature and under harsh chemical conditions. Because they reside within an atomically thin 2D material, these QEs have a unique potential to couple strongly to hybrid optoelectromechanical and quantum devices. However, this potential for coupling has been underexplored because of challenges in nanofabrication and patterning of hBN QEs. Motivated by recent studies showing that QEs in hBN tend to form at edges, we use a focused ion beam (FIB) to mill an array of patterned holes into hBN. Using optical confocal microscopy, we find arrays of bright, localized photoluminescence that match the geometry of the patterned holes. Furthermore, second-order photon correlation measurements on these bright spots reveal that they contain single and multiple QEs. By optimizing the FIB parameters, we create patterned single QEs with a yield of 31%, a value close to Poissonian limit. Using atomic force microscopy to study the morphology near emission sites, we find that single QE yield is highest with smoothly milled holes on unwrinkled hBN. This technique dramatically broadens the utility and convenience of hBN QEs and achieves a vital step toward the facile integration of the QEs into large-scale photonic, plasmonic, nanomechanical, or optoelectronic devices.

Site-Specific Fabrication of Blue Quantum Emitters in Hexagonal Boron Nitride

Hexagonal boron nitride (hBN) is widely used as a protective layer for few-atom-thick crystals and heterostructures (HSs), and it hosts quantum emitters working up to room temperature. In both instances, strain is expected to play an important role, either as an unavoidable presence in the HS fabrication or as a tool to tune the quantum emitter electronic properties. Addressing the role of strain and exploiting its tuning potentiality require the development of efficient methods to control it and of reliable tools to quantify it. Here we present a technique based on hydrogen irradiation to induce the formation of wrinkles and bubbles in hBN, resulting in remarkably high strains of ∼2%. By combining infrared (IR) near-field scanning optical microscopy and micro-Raman measurements with numerical calculations, we characterize the response to strain for both IR-active and Raman-active modes, revealing the potential of the vibrational properties of hBN as highly sensitive strain probes.

Vibrational Properties in Highly Strained Hexagonal Boron Nitride Bubbles

The existence of buried oxide (BOX) layer and the strong coupling effect between the front and back channels can worsen the radiation-induced degradation on fully depleted silicon-on-insulator (FDSOI) device. To mitigate the radiation impact, a new structure named double SOI is introduced in this paper. This new structure exhibits potential benefits of reducing the radiation-induced degradation effectively and independently, thanks to the additional electrode, which can be used to control the internal electrical field of the BOX layer. With this structure, FDSOI device parameter degradation due to total dose is studied, and some abnormal phenomena, such as the transconductance hump and the mobility enhancement, are observed and discussed. Sentaurus TCAD simulations are used for further analysis. Moreover, the impact of negative back-gate bias to transistor parameter degradation is investigated, and an improved back-gate compensation strategy is proposed. Technology improvement such as thinning the BOX on total ionizing dose (TID) amelioration is also discussed with TCAD simulation.

The total ionizing dose response of leading-edge FDSOI MOSFETs

Charge trapping in the buried oxide can lead to serious back-channel leakage and make SOI (Silicon-on-Insulator) transistors more sensitive to total dose radiation. In this paper, a new DSOI (Double SOI) transistor is proposed, which utilizes the method of back-gate biasing to force an external electric field, and then depress the back channel formation during total dose irradiation. The simulation and testing results both indicate that, for a given structure, when a −3V bias is applied to the back-gate, the DSOI transistor can tolerant a total dose radiation of 500k rad(Si). This methodology fits all kinds of SOI MOSFETs, especially for the Fully-Depletion SOI transistors. With commercial (not especially hardened) buried oxide, DSOI device can have better radiation hardening performance than its both companions - FDSOI and PDSOI transistors.

DSOI FET - A novel TID tolerant SOI transistor

The effects of proton irradiation on the electrical and optical properties of hybrid perovskite photodetectors have been investigated in this paper. Our results reveal that no significant changes in the photoelectric properties of the perovskite photodetectors are observed when the proton fluence accumulates to 1 × 1012 p cm−2. However, with further increase of proton fluence, the photoelectric conversion efficiency of the perovskite photodetectors begins to decrease notably. This can be attributed to the introduction of deep defect levels within the bandgaps of the CH3NH3PbI3 active layer and the phenyl-C61-butyric acid methyl ester (PCBM) layer after proton irradiation. Based on time-resolved photoluminescence measurements, the deep defect levels in the active layer behave as nonradiative recombination centers, resulting in a reduction of carrier lifetime. According to our first-principles calculations, the deep defect levels in the PCBM layer act as electron trap centers, leading to an accumulation of photo-generated electrons. Most interestingly, when the proton fluence reaches 1 × 1014 p cm−2, a transient inverse current in the perovskite photodetectors is observed after stopping illumination. This abnormal phenomenon is due to the accumulation and release of electrons trapped in the PCBM layer, which can diffuse to the perovskite active layer and form the inverse current.
