- •
An amorphous YBaCuO planar infrared detector was designed, fabricated and tested.
- •
UPS confirmed the possible Schottky nature of the amorphous YBaCuO–metal contacts.
- •
The device exhibited a high-pass pyroelectric fast response extending up to the MHz.
- •
The response was explained by an analytical model, without adjustable parameters.
- •
The IR detectivity, close to the theoretical limit, showed the device competitiveness.
