M.IN. D (Manoj Infrared Detector's) Foundry

Research and development of Low-dimensional Heterostructures & quantum Materials for detectors 

MIND Foundry is a research and development (R&D) team. We work on group III-Nitride (GaN-based) and III-Antimonide (GaSb-based) quantum materials for infrared detectors spanning from 1 μm (SWIR) to 14 μm (LWIR) wavelength range.

If you want to collaborate with the MIND foundry, don't hesitate to contact me...



Open position in MIND foundry:


















M.I.N.D (Manoj Infrared Detector's) foundry is a team of:

Crystal growers: Utilize the state-of-the-art Veeco Gen 930 Molecular Beam Epitaxy (MBE) for developing the epitaxy of novel Compound Semiconductors materials and devices.

Device fabrication experts: Design, simulate, model and fabricate detectors in single-pixel and array format using  a class 10, 100 and 1000 cleanroom.

MIND team perform epitaxy, theoretical simulation, fabrication/processing of low dimensional hetero-structures, quantum 1D wires, dots (QD), Quantum well (QW), Complex Quantum Wells CQW -Type-II strained layer super-lattice (T2SL) and Digital alloys (ES). Fabricate detectors working in NIR to LWIR wavelength regime for sensing, detection, thermal imaging.

Ongoing research projects:

1)  EPSRC  Monolithic On-chip Integration of Electronics & Photonics Using III-nitrides for Telecoms

2) Innovate UK - Quantum Electro-optic Detector Technology (QuEoD)

3) Horizon 2020 EU- MSCA-ITN-2020- Innovative Training Network - QUANTIMONY-Quantum Semiconductor Technologies Exploiting Antimony

4. DASA (ACC20244551) Type-II superlattice Photodiode array for infrared sensing


a) A.D.E (Advanced Detectors Epitaxy) Laboratory

ADE laboratory has state-of-the-art Veeco Gen 930 MBE reactors dedicated to III-As(Sb) epitaxy with triple-zone valve group V crackers equipped with 3" substrate heater with 12000C  temperature operation and ~ 2-degree control. The reactors also ideally suited for undertaking the growth of novel Bi, N containing dilute bismides, dilute Nitrides and highly mismatch alloys (HMA). A Pananlytical XPert high-resolution x-ray diffractometer (HRXRD) with fast 8-inch wafers reciprocal space maps (RSM) capability.

b) A.D.C (Advanced Detector Characterisation) Laboratory

ADC laboratory host a complete detector characterisation facility with electrical characterisation tools (picoammeter, LCR meter, semiconductor device analyser, spectrum, and network analysers, noise figure meters and 50 GHz network analyser), FTIR-PL and photo-response set-up and a cryogenic probe station.
