Review of essential use of fluorochemicals in lithographic patterning and semiconductor processing
By Technical Paper Link - 06 Apr, 2022 - Comments: 0

New academic paper by researchers from Cornell University.   Abstract "We identify and describe categories of fluorochemicals used to produce advanced semiconductors within the lithographic patterning manufacturing processes. Topics discussed include the per- and polyfluoroalkyl substance (PFAS) materials used and their necessary attributes for successful semiconductor manufacturing... » read more

Highly efficient modulation doping: A path toward superior organic thermoelectric devices
By Technical Paper Link - 05 Apr, 2022 - Comments: 0

New academic paper from TU Dresden. Abstract "We investigate the charge and thermoelectric transport in modulation-doped large-area rubrene thin-film crystals with different crystal phases. We show that modulation doping allows achieving superior doping efficiencies even for high doping densities, when conventional bulk doping runs into the reserve regime. Modulation-doped orthorhombic rubr... » read more

Quantum logic with spin qubits crossing the surface code threshold
By Technical Paper Link - 04 Apr, 2022 - Comments: 0

New research paper from QuTech, Delft University of Technology. Abstract "High-fidelity control of quantum bits is paramount for the reliable execution of quantum algorithms and for achieving fault tolerance—the ability to correct errors faster than they occur. The central requirement for fault tolerance is expressed in terms of an error threshold. Whereas the actual threshold depends o... » read more

A novel technique for random number generation using CMOS image sensor
By Technical Paper Link - 04 Apr, 2022 - Comments: 0

Academic paper from Thamirabharani Engineering College, India. Abstract "Random Number Generators (RNGs) have been used in several traditional fields such as simulation, gaming, cryptography, etc. Random numbers are used in cryptography to generate passwords. The strength of a password depends not just on its length and complexity but mainly on its unpredictability. Strong passwords lower t... » read more

Academic paper from Lawrence Livermore National Laboratory (LLNL) scientists in collaboration with San Francisco State University and the The Pennsylvania State University. Abstract "Although multiple oxide-based solid electrolyte materials with intrinsically high ionic conductivities have emerged, practical processing and synthesis routes introduce grain boundaries and other interfaces t... » read more

NIST Modifies & Improves Technique For Detecting Transistor Defects
By Technical Paper Link - 04 Apr, 2022 - Comments: 0

Abstract "We utilize a frequency-modulated charge pumping methodology to measure quickly and conveniently single “charge per cycle” in highly scaled Si/SiO2 metal–oxide–semiconductor field effect transistors. This is indicative of detection and manipulation of a single interface trap spin species located at the boundary between the SiO2 gate dielectric and Si substrate (almost certainl... » read more

Low-cost and Stable SFX-based Semiconductor Materials in Organic Optoelectronics
By Technical Paper Link - 04 Apr, 2022 - Comments: 0

Abstract: "In the progress of realizing the commercialization of organic optoelectronic materials, the four basic coherent factors are stability, cost, performance, and processability, all which determine the results of device applications. Spiro[fluorene-9,9′-xanthene] (SFX) has been becoming the robust building-block that fulfilling the practical requirements due to its key features of non... » read more
