Structural and dimensional characterization of layered structures in semiconductors is increasingly important for microelectronics manufacturing because of the continuing downward scaling of devices. Manufacturers require high-precision non-destructive
A series of recent studies asserted that near-interface-traps (NITs) are introduced by the post-oxidation NO annealing process and these NITs are the cause for the low mobility of NO annealed SiC MOSFETs. We use fast Id-Vg measurement to directly probe
In this work, we propose a comprehensive framework to analyze threats related to semiconductor supply chain. The framework introduces a metric which quantifies the severity of different threats subjected to a collusion of adversaries from different stages
Within an optical nanocavity, the temperature dependence of the emission wavelength defines its emission energy stability. Thermal management, therefore, is crucial in controlling wavelength drift and/or radiative recombination rates, especially in

The 18R polytype of SnSe2 possesses unique structural features that can directly impact the transport properties and potential applications of interest; however, a comprehensive understanding of the intrinsic physical properties is lacking. We grew large
Deposition of carbonaceous material under electron beam irradiation is an old and persistent problem of scanning electron microscopy. It is an impediment to high-resolution imaging and measurements, especially at the nanometer-scale. The emergence of
This report of the Semiconductors and Microelectronics Standards Working Group of the Interagency Committee on Standards Policy (ICSP) provides an overview of Federal government semiconductors and microelectronics standards activities and recommends

Previously we reported a compact one-transistor (1T) 180 nm bulk CMOS cryo-memory with a high 10^7 I_1/I_0 memory window and long 800 s retention time based on impact-ionization-induced charging of the transistor body. Here, we present the endurance and
Interface defect response time is a key parameter in some common electrical measurements of MOS devices, most notably the hi-lo CV measurement as well as the conductance measurement. A long established believe is that interface defects at energies close to
