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)…

θ-Tunable Photoluminescence from Interlayer Excitons in Twisted Bilayer Graphene
Hiral Patel, Lujie Huang, Cheol-Joo Kim +2
Using resonant 2-photon excitation of interlayer electrons in twisted bilayer graphene (tBLG), we resolve photoluminescence (PL) that tunes spectrally with stacking angle, θ. This…
