Listing
April 2014 — Haydale AIM (HAYD). About US$11 million gross in contemporaneous copy; convert the sterling RNS when attaching it. Plasma-functionalization story, not a 4,000 t mill. haydale
Photodetectors
- Liu, Chang, Liu, Zhong, Nat. Nanotechnol. 9, 273 (2014). Double-layer graphene heterostructure phototransistor. Room-temperature visible-to-mid-IR; mid-IR responsivity >1 A/W in that report.
- Koppens, Mueller, Avouris, Ferrari, Vitiello, Polini, Nat. Nanotechnol. 9, 780 (2014). Review of graphene / 2D / hybrid photodetectors — the field’s map after the 2013 waveguide cluster.
- Cai, et al., Nat. Nanotechnol. (2014) photothermoelectric THz detector: room-temperature THz class, speed claim vs then-existing room-temp THz parts. Still a lab detector.
These sit with 2013 waveguide PDs. None is a catalogue SKU.
Flagship / quality talk
Roadmaps published. Sheet resistance and Raman I(2D)/I(G) start appearing in the same sentence as “graphene.” ISO vocabulary still 2017. iso-vocabulary
