Shallow Trap States Control Electrical Performance of Amorphous Oxide Semiconductor Thin-Film Transistors
Måns J. Mattsson, Jinhan Lee, Christopher E. Malmberg +10
The performance of n-type amorphous oxide semiconductor thin-film transistors (TFTs) is largely controlled by the density of states (DoS) near the conduction band mobility edge. He…
Illuminating trap density trends in amorphous oxide semiconductors with ultrabroadband photoconduction
George W. Mattson, Kyle T. Vogt, John F. Wager +1
Under varying growth and device processing conditions, ultrabroadband photoconduction (UBPC) reveals strongly evolving trends in the defect density of states (DoS) for amorphous ox…
High symmetry anthradithiophene molecular packing motifs promote thermally-activated singlet fission
Gina Mayonado, Kyle T. Vogt, Jonathan D. B. Van Schenck +4
When considering the optimal molecular packing to realize charge multiplication in organic photovoltaic materials, subtle changes in intermolecular charge transfer (CT) coupling ca…
Hydrogen incorporation into amorphous indium gallium zinc oxide thin-film transistors
George W. Mattson, Kyle T. Vogt, John F. Wager +1
Within the subgap of amorphous oxide semiconductors like amorphous indium gallium zinc oxide (a-IGZO) are donor-like and acceptor-like states that control the operational physics o…
Ultrafast photocurrent and absorption microscopy of few-layer TMD devices isolate rate-limiting dynamics driving fast and efficient photoresponse
Kyle T. Vogt, Su-Fei Shi, Feng Wang +1
Despite inherently poor interlayer conductivity, photodetectors made from few-layer devices of 2D transition metal dichalcogenides (TMDs) such as WSe and MoS can still yiel…
Ultrabroadband Density of States of Amorphous In-Ga-Zn-O
Kyle T. Vogt, Christopher E. Malmberg, Jacob C. Buchanan +6
The sub-gap density of states of amorphous indium gallium zinc oxide (-IGZO) is obtained using the ultrabroadband photoconduction (UBPC) response of thin-film transistors (TFTs)…
