Supervised learning applied to high-dimensional millimeter wave transient absorption data for age prediction of perovskite thin-film
Biswadev Roy, A. Karoui, B. Vlahovic +1
We have analyzed a limited sample set of 120 GHz, and 150 GHz time-resolved millimeter wave (mmW) photoconductive decay (mmPCD) signals of 300 nm thick air-stable encapsulated pero…

Characteristics of room temperature bipolar photoconductance in 150 GHz probe transients obtained from normal and irradiated silicon illuminated by 532 nm laser
Biswadev Roy, Branislav Vlahovic, Marvin H. Wu
A negative kink in excess conductivity is observed in p-type non-degenerate (moderate dopant concentration) silicon wafers when excited by a very narrow pulse of 532 nm laser appea…

Biological effects of low power nonionizing radiation: A Narrative Review
Biswadev Roy, Suryakant Niture, Marvin H. Wu
Background and controlled electromagnetic radiation (EMR) on biological cells and tissues induces thermal, non-thermal, and dielectric property change. After EMR interaction with c…
