Cardiff University International Scholarship


I am a Lecturer (Teaching and Research), group leader of the M.I.N.D research group and a CMP outreach representative in the School of Physics and Astronomy, Cardiff University.

Epitaxy: I have used Molecular Beam Epitaxy (MBE) for the growth of GaN, GaSb, GaAs, InAs and their alloys based low dimensional quantum heterostructures for near and mid-infrared emitters and detectors. Such as InAsN/InGaAsN MQW, metamorphic buffer layer (MBL), resonant tunnelling diodes (RTD) of InAsN/InAlAs, InAsSbN/InAs photodiode and InAs/InAsSb type-II superlattice LED, In (As/Sb) (TPV). High In containing InGaN, GaN and InN thin-film, nanowires and device structure and II-VI lattice-matched buffer development for high In InGaN APDs.

Fabrication: InAs, InGaAs, InGaAsBi, and III-Sb based photodiodes and avalanche photodiodes (APD) and have performed electrical characterization.

Who am I... What I do...

I am a group leader of the M.I.N.D (Manoj Infrared Detector's) research group.

I am a crystal grower, use state-of-the-art Molecular Beam Epitaxy (MBE) for developing the epitaxy of novel Compound Semiconductors materials and devices. I create submonolayer Ultra-thin films, Thin films, Quantum wires (atomic chains on faceted high-index Silicon), Quantum well (QW), Complex Quantum Wells (Type-II Superlattice (SL), Digital alloys), Quantum dots (QD), Nanostructures (nanowires, nanocolumns). I simulate, model and design devices such as detectors, emitters and thermophotovoltaics and fabricate devices in a single-pixel and array format. perform lithography, metallization and packaging in class 10, 100 and 1000 cleanroom.

My research focus is on heteroepitaxy and fabrication of compound semiconductors devices:

i)  Detectors and Emitters operating in NIR to LWIR wavelength range for sensing, detection, thermal imaging. Device types are Light-emitting diodes (LED), photodiodes (PD), avalanche photodiode (APD) and staring/focal plane array (FPA).

ii) Thermophotovoltaic (TPV) cells for the resilient silent waste heat energy recovery and Solar-Thermo PhotoVoltaic (STPV) for energy harvesting.

iii) Photovoltaic-photoelectrochemical cells (PV-PEC) for hydrogen generation and water purification via solar energy.

I am in charge and manager of -

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 and III-Nitride epitaxy both reactors are equipped with 3” substrate heater with 1200  temperature operation and ~ 2-degree control. The MBE system is also ideally suited for undertaking the growth of novel Bi, N containing dilute bismides, dilute Nitrides and highly mismatch alloys (HMA). It also has a Pananlytical XPert high-resolution x-ray diffractometer (HRXRD) with fast 8-inch wafers reciprocal space maps (RSM) capability.

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.

My ongoing research projects:

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

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

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

4) EPSRC GCRF-IAA funded. Photo-electro-catalytic (PEC) reactor and testing different photo-active catalysts for degradation of recalcitrant organic pollutants from wastewater
