Transition metal dichalcogenide (TMD) monolayers are promising channel materials for next-generation electronic devices. A challenge is the high contact resistance between monolayer TMDs and metal contacts, especially for holes. In this regard, raised source/drain contacts are promising. However, the direct, patterned growth of raised contacts at CMOS-compatible temperatures remains largely unresolved. We present plasma-free selenization and sulfurization of metal oxides at substrate temperatures down to 400 °C, compatible with back-end-of-line thermal budgets. To achieve growth at such...

BPNX1054: Tungsten Oxide Adhesion Layer for Low Resistance Hole Contacts to WSe2

Transition metal dichalcogenides (TMDs) are promising candidates for rapidly scaled, high-performing devices due to their atomically thin nature. However, the dangling bond-free surfaces of TMDs fundamentally challenge the creation of strongly bonded metal contacts. Here, we introduce tungsten oxide (WOx) as an interfacial adhesion layer for low-resistance hole contacts on monolayer WSe2. We show that the WOx adhesion layer exhibits a two-fold increase in adhesion force on both WSe2 and SiO2 surfaces and a twofold reduction in total resistance compared to devices with conventional titanium...

BPNX1058: Visible-to-Mid-Infrared Photodetection with Self-Adaptive Responsivity-Speed Tradeoff

Normal scenes captured by cameras involve light intensities spanning more than five orders of magnitude, which is often taken care of with auto-exposure/multiple exposures in high dynamic range (HDR) imaging technologies. Such technologies assign one or several uniform exposure levels and dynamic ranges for all pixels in the image, significantly squeezing the data precision for dimmer regions, causing fundamental information loss at the photodetection stage.


Ideally, each detector should independently decide its tradeoff between responsivity and speed. For...
