Photoresponse investigation of polycrystalline gallium antimonide (GaSb) thin films

AIP Advances, 2020
Thin films of polycrystalline gallium antimonide (GaSb) were grown on widely available mica substrates using the physical vapor deposition method. The as-grown films contain grains of nano-scale with regular symmetries, as identified by x-ray diffraction

Human and Intellectual Capital Spending Efficiency and Efficacy: Evidence from U.S. Universities

Journal of Business Finance &Accounting, Volume 53, Issue 2, Page 970-997, April 2026.
ABSTRACT We analyze the efficiency and efficacy of human and intellectual capital investment to better understand the effects of social investment. Existing literature in the corporate setting lacks analysis on the impact of human and intellectual capital investment, likely due to data scarcity.

PearSAN: A Machine Learning Method for Inverse Design Using Pearson Correlated Surrogate Annealing

Advanced Optical Materials, Volume 14, Issue 10, 13 March 2026.
A machine learning–assisted inverse design framework is introduced to overcome the curse of dimensionality in complex nanophotonic design problems. By leveraging Pearson‐correlated surrogate annealing (PearSAN) method within a generative latent space, rapid convergence toward optimal thermophotovoltaic metasurface designs is achieved, enabling precise ...

Gate-controlled semimetal-topological insulator transition in an InAs/GaSb heterostructure

, 2015
We report a gate-controlled transition of a semimetallic InAs/GaSb heterostructure to a topological insulator. The transition is induced by decreasing the degree of band inversion with front and back gate voltages.
